How often has this scenario happened to you?

Armed with your short grocery list, you head to your favorite grocery store. You buy two items from your list: a head of lettuce and a BPA-free can of tomatoes. The store was out of sour cream, so you swing into another store on the way home, a store that you don’t regularly shop at.

As you head to the dairy section, you happen to walk past the canned tomatoes. One can, in particular, catch your eye because it’s the same can you just bought. A closer look reveals an “everyday low price” that is 50¢ cheaper than the other store!

You’re a bit speechless that this unfrequented store has a better price on something you buy so often… and you’re a bit upset too, thinking about all the times you’ve paid 50¢ too much on a can of tomatoes… and how much money you could have saved if you only knew that this store was cheaper.

I’m going to go out on a limb here and guess that it’s happened more times than you can admit. The same goes for me too.

Fortunately, there’s a SUPER easy way to avoid this situation from happening again, and it’s called a supermarket price comparison book.


Simply put, a supermarket price comparison book (or price book for short) is a little “book” that records the prices you pay for certain items. It can be electronic (like an app), typed and printed (like a spreadsheet), handwritten on a few pieces of paper, jotted down in a spiral notebook, or even recorded in a full-fledged binder with removable sheets of paper.

In any case, a supermarket price comparison book is an absolute MUST-HAVE if you’re new to grocery budgeting, trying to reduce your grocery budget, or struggling with staying within your allotted means. And I think that pretty much covers us all.

Working on improving your grocery budget takes several steps and creating a supermarket price comparison book is one of them!

How Much Money Can a Supermarket Price Comparison Save?

No doubt, some of you are skeptical, wondering if a few pages of torn notebook paper stapled together haphazardly are worth the effort in the first place. You might be wondering if they’re worth it in the long run.

I’m sure an excuse or two has found itself meandering around in your brain, tempting you with one reason or another why you shouldn’t do it. Do any of these sound familiar?

You can remember what you paid and don’t need to write it down.

Maybe you can. But for how long? How many items? Can you remember what you paid for a can of pinto beans a year ago? Points to you if you have an elephant memory, but you’re the minority. Most of us can’t remember what we paid for the beans, chicken, tomatoes, and lettuce that we bought just last week!

You don’t want to waste gas, driving all over town for prices.

Then don’t! Just keep track of the different stores you’re already shopping at. If you aren’t going to Trader Joe’s this week, then don’t worry about it. Make a note the next time you’re there. You don’t have to know the price of every item, from every store, by tomorrow. Supermarket price comparison books are a long-term savings strategy. A war, not a battle.

Supermarket price comparison books won’t help because you eat 100% organic and you have food allergies.

Oh, my sweet friend, supermarket price comparison books can help you out the most! Organic and specialty items are “hot” items, and some stores mark them up by a dime or two to increase their profit. Besides, aren’t these items more expensive in general? Even more reason to shop for the best deal you can, right?

You don’t have time. Not even 15 minutes. You promise.

Okay, then. So, you’re telling me that from the moment you rise to the moment to go to bed, you can’t possibly squeeze 15 minutes out of your day. But not even 10? Or five? Two?! It’s obvious that since you’re reading this blog, you’re trying to save money and eat healthier foods…But spending five minutes recording a few numbers from your shopping trip this week – a small yet incredibly effective money-saving technique – is not important enough to make it on your weekly task list? Need I remind you how much can really be done in a mere two-minute time frame?


There are LOTS of ways to make the concept of a store price comparison way more complicated than it needs to be, but I’m all about keeping it simple whenever possible. With that said, here’s how you set up a basic grocery price book:

Step 1. Choose a Tracking Method

I recommend using a pencil and paper. There’s extra learning power when we write something by hand since it tends to stick in our memories better. Plus I think writing is more intentional than typing, especially when it’s so easy to hit “save” only to never open it again.

The whole purpose of writing down supermarket price comparison is to USE it, so if you’re more Apple or Android than Papermate, then go electronic. I just think the old-fashioned method is the best way to do this.

If you agree, here are three frugal ways you can quickly and easily pull together some paper for a supermarket price comparison book. Choose the method that best fits with what you have on hand and that’s easiest.

  • A few sheets of notebook paper, folded into fourths and stapled into a book (be sure to cut any folded pages so that they fold properly)
  • Use a dedicated spiral notebook (small or large and CHEAP, from the dollar store or similar)
  • A handful of pages within a notebook are used for similar purposes (like the notebook where you keep your meal plans, shopping lists, etc.)

Step 2. Set-up Your Pages

Depending on the size of your notebook, you’ll want to designate one page (if the book is small) or half a page (if the book is big) for each particular item you’re going to track.

For each item, you need to record just five small pieces of information: Date, Store, Brand, Total Price per Size, and Price per Unit.

  • Date: Self-explanatory, but this is the date you bought the item. Many items are seasonal, but not everything is. Knowing the date you bought something could help determine when the best deals might come along.
  • Store: The store you bought it at. Be specific and include the location if you shop at the same store in different areas.
  • Brand: Tracking this will help you recognize what brands tend to be less expensive than others. This information can also be handy later when the budget is under control and you’re ready to research the quality of the brands you regularly buy.
  • Total Price per Size: This is the total of what you paid for the size of the item. For example, $2.50/15oz of organic canned tomatoes.
  • Price per Unit: This is the price per unit of the item, as in per ounce, per milliliter, per pound, per bar, etc. For example, 17¢/oz of organic canned tomatoes, or $2.15 per KIND bar.

Make five columns on 10 pages (or five half pages) for each of these and label them at the top.

Step 3. Track 10 Items

Part of having a frugal grocery budget series includes keeping your receipts, but here is another way they come in handy (besides categorizing your spending)!

Go through your receipts and choose 10 items that you buy the most often. Give each one a page (or half page) in your book. For example, every month we buy the following items:

  • Organic whole chickens
  • Organic whole milk gallons
  • Cheese (organic)
  • Bananas
  • Oranges
  • Organic kale
  • Apples
  • Fresh mozzarella
  • Pepperoni
  • Peanut butter

At the top of each page (or half-page), identify the item you’re tracking. Then, fill in the information in the columns using the receipts you have on hand. You might have to check the packages in the kitchen for some of it (like the total ounces of cheese, or total pounds in each chicken), but fill out as much as you can. The more information, the better.

Step 4. Repeat Step 2 (Next Week)

Most people will tell you to add to your supermarket price comparison book every time you go shopping… to review your receipts and take the time to give every item its own page (or half-page) and record the required information. One blogger recommends setting aside 10 hours a week to work on a supermarket price comparison book. Another gal says to spend five.

Not me. I don’t have extra hours in my week to spend on this, and I’m betting you don’t either. In my opinion, it’s best to spend just 15 minutes and track the items you buy most often.

For example, if you only buy blue cheese and water crackers when your mom visits at Christmas, there’s no point in tracking those prices all year. However, if you buy canned tomatoes and spinach weekly, you would benefit by keeping track of what you paid and who has the best price.

So here’s what I propose: Make it a goal to add or update 10 items each week to your list price. These can come from your receipts from grocery circulars or even online bloggers who share the price of certain items from certain stores.

Should you read the circulars if you have no intention of buying? Absolutely! It’s a SUPER easy way to learn the price of items without ever stepping foot in the store. Then when you ARE ready to buy, you know how much (or how little) it can be purchased for.

Step 5. Shop According to the Supermarket Price Comparison Book

Finally, it’s time to put your book into action. Before buying something, or even adding it to your grocery list, consult your supermarket price comparison book.

  • Has the price of canned garbanzo beans steadily gone up? Maybe it’s time to look into dry beans instead.
  • Grass-fed ground beef is on sale this week but your recipe calls for a more expensive ground turkey? Swap the meal plan (or just substitute!).
  • Are strawberries on sale? Check your supermarket price comparison book to see if the deal is worth spending your money on!

One money-saving method is “learn to stockpile,” but within that method, there’s this:

When an item you know you’ll use (shampoo, conditioner, lotion, razors, etc.) is free or on a discount, or very inexpensive (using any combination of store sales, coupons, and/or rebates), then you buy enough at that price to last a specific amount of time.

Granted, when your funds are SUPER tight each month, buying one extra of anything is a huge feat. However, let’s concentrate on that first line for a moment: “… is free or very inexpensive…”

This small statement implies that you know when an item is overpriced. How exactly do you know this? You keep a supermarket price comparison book! Tracking the price history really saves time and money.


Let’s talk numbers. After all, that’s what we ultimately need this supermarket price comparison book to do – save us money – right?

Let’s take five items that we (my family) buy monthly and put them to use in a grocery store price list.


Trader Joe’s sells whole organic chickens for $2.69/lb. Every month I buy two whole chickens, and the combined weight is roughly 10 pounds.

Costco sells whole organic chickens for $2.49/lb.

If I bought these chickens from Costco instead of Trader Joe’s, I could have saved $24 over the course of one year.


On average, organic apples cost $1.75 per pound at Costco. Every week I buy approximately five pounds of apples.

When they’re in season, local organic apples are available at the farmer’s market for just $1.25 per pound.

When they’re not in season, organic apples are available at various stores in my area for $1.50 per pound, sometimes less.

If I bought organic apples from the farmers market instead of Costco during peak season, I could have saved $32.50.

If I paid attention to sales and bought from the store with the best price for the rest of the year, I could have saved $48.75.

Combined, this would be a savings worth $81.25 in one year.

Local grocery stores sell one dozen organic eggs for $4.99. We eat approximately two dozen eggs each month.

A local discount grocery store sells a 20-count package of organic eggs for $4.79.

If I bought organic eggs from a discount grocery store instead of the supermarket, I could have saved $51 over the course of one year.


Only a few local grocery stores sell dried black beans and those that do charge $1.69 for one pound. We eat approximately one pound of black beans each month.

A local ethnic market sells dried black beans for just 99¢.

If I bought dried beans from the local ethnic market instead of the supermarkets, I could have saved $12.50 over the course of one year.


The best deal in my area for couscous is buying it in bulk from Whole Foods. They charge $2.99/lb for couscous, and we eat approximately one pound of couscous each month.

Amazon sells a large 10 lb bag of couscous for just $1.36/lb.

If I bought couscous in bulk from Amazon instead of from Whole Foods, I could have saved $19.50 over the course of one year.


And that was for just five items. Just five!

Imagine how much money you could save if you tracked 10 items… or even 15!

Imagine how much money you could save over the course of time if you slowly kept track of your purchases, diligently recorded the different prices, and made a purposeful effort to shop for the best deals as often as you could. My mind is spinning with the endless savings possibilities!

So many people ask me how we afford to feed four mouths for just $330 every four weeks. Using a supermarket price comparison book is one way we accomplish this, along with these tips:

  • buy when it’s a great, low price
  • always seek a better deal
  • don’t become complacent with the prices you pay
  • compare local stores to online stores
  • be open to new, unfamiliar stores
  • be open to new brands
  • don’t assume farmers markets are more expensive
  • don’t assume buying in bulk is cheaper
  • know what foods are “must haves” in your house
  • know what foods you can live without if there isn’t a good deal


How can you compare prices at the grocery store to determine the best value?

Make a supermarket price comparison book! Follow the steps in this post to track the items your family buys most.

Which is the cheapest grocery store?

The best grocery store for you to shop at will depend on what items your family buys the most, if and how often those products go on sale, and if you want to buy everything at one store or shop around at a few places. You can track all of that in a supermarket price comparison book to find the best grocery store for you to shop at.

Is there an app for grocery price comparison?

There are a few apps that offer grocery price comparison, but some only pull from weekly sales ads and don’t include regular prices, and most don’t consider coupons or cash-back rebates. Store loyalty cards can also give you added discounts that may not be shown on a grocery price comparison app. A supermarket price comparison book will be your best bet for a price list of grocery items you’re going to use.
A few apps worth checking include:

Grocery King
Grocery Pal
• Price Cruncher (Check your Android App Store)

Can I use a supermarket price comparison book for online grocery shopping?

Yes! As buying groceries online for delivery or pick up has become more popular, most stores have an online shopping option. Kroger, Wegmans, Meijer, Safeway, and Publix have their own online shopping. Instacart is another one where you can shop at multiple stores online.

You can use their online prices to build your supermarket price comparison book if you regularly shop online. I will warn you though, I have seen large differences in in-store prices vs. online. The BEST prices still tend to be in-store.


Supermarket price comparison books don’t have to be fancy. Or complicated. They just need to work for YOU. If my method above seems like too much work and you have a comparison app that does the trick, then by all means – use it! Supermarket price comparison books can be a tremendous help to compare supermarket prices and to see trends and the true cost of items. The most important thing for you to do is to just get one and use it!
