The best items to buy at Costco to save money!
Years ago I signed up for my very first Costco Membership. I had heard all about the best deals at Costco and how it could help save me money. The first time I walked into the store I was so excited to start saving money.
I spent an hour walking through aisle after aisle in the store filling my shopping cart with all of my new fun finds and I couldn’t wait to see how much money I was saving. The beautiful organic produce, the cute kids clothing, and all those snacks! Oh, was it fun!
And then, I went to checkout.
My jaw about dropped to the floor when the cashier announced that I owed over $300. “What about all those good deals I grabbed. I thought shopping in bulk would save me money!” were the thoughts that swirled in my head as I shakily swiped my credit card and the spending guilt set in.
After repeating this process for a few months I realized that my grocery budget was suffering, big time, and Costco was NOT saving me money. I cancelled my membership and never looked back.
Fast forward ten years, and a bunch of new frugal lessons learned, I decided I wanted to try out Costco again. But this time, I was going to be using my card with a new, better approach.

The Wrong Way To Shop Costco
Here’s the thing, there is a wrong way and a right way to shop at Costco. If you want to spend less money at Costco, it’s so important for you to understand the differences.
Here are a few of the wrong ways to shop at Costco:
Shopping when hungry.
Don’t ever shop at Costco with an empty stomach (I learned this the hard way!). You will be much more tempted to grab more food than you really need.
Assuming that buying in bulk is cheaper.
The truth is buying your food in bulk CAN be cheaper, but not always. Always check the price per unit to help you decide which is the better deal.
Buying more food than you can eat before it spoils.
Before you buy anything at Costco, I recommend you think long and hard about how quickly you can eat the item you are buying. If you buy a huge pack of spinach, but your family can’t eat it before it goes bad, then unfortunately that spinach gets thrown away, meaning your hard earned money goes to waste.
Shopping without a plan.
Going into Costco without a plan is a quick way to break your budget. Aimlessly wandering aisle after aisle is a huge temptation to many of us (ME!) and should be avoided as much as possible.
Assuming that the sales are a good price.
I LOVE most of Costco’s monthly sale items (hello cheap Premier Protein shakes), but I have learned that just because something is on sale, does not make it a great price.
Like I mentioned earlier, it’s necessary to always check the price per unit before buying something. I like to compare Costco prices to Walmart Grocery Pickup prices using their phone app. This helps me know if I can find the same item cheaper somewhere else.
The Right Way To Shop Costco
Alrighty, now let’s talk about the RIGHT way to shop at Costco. Following these tips will help you get the most out of your Costco membership and not have to leave the store with a mountain of guilt.
Set a budget.
If you don’t already make a regular budget, I suggest you start one now. A budget gives you permission to spend, without the guilt; but it also decreases the chance of impulse buying.
Give yourself a budget for how much you can spend at Costco each month. My personal budget is $100/month.

Always shop with a list.
Make a list of items you want to purchase at Costco BEFORE going into the store. If you shop with a list in hand you will be much more likely to stick to it and avoid any impulse shopping.
Research the current deals, and what you need at that time. A good rule of thumb is to plan about $10/item. Of course this number varies based on what you buy, but it gives me a good goal to work towards.
Use a calculator.
Yes! I am totally *that* person walking around Costco with my calculator, adding up everything before putting it into my cart. And honestly, it has saved me from overspending so many times!
Add up everything as you put it into your cart to make sure you stay in budget and there won’t be any surprises when checking out.
Know what is a good deal or not.
Like I mentioned earlier, it’s important to check the price per unit of items before you buy them. I recommend grabbing my free Stock Up Price Guide here to help you learn the best deals of popular food items.
Take a picture of the price guide so that you always have it with you while shopping. Check it often to help you compare food items before buying them.

Here is my list of my favorite deals at Costco. Most of these items I buy every single time I go to Costco. Other items I have just noticed that the price is great!
1. Rotisserie Chicken
I am so in love with Costco’s Rotisserie Chicken. It’s moist, delicious and a great deal for only $4.99. This rotisserie chicken is always at the top of my Costco shopping list.
- Rotisserie Chicken at Costco: 10 cents/oz.

3. Butter
Another one of the best deals at Costco is their butter. I always buy this 4 lb. pack of butter. I store 1 lb. in my fridge and the other 3 lbs. are kept in my freezer until I needed. Today my local Costco has their 4 lb. butter for $6.95, making it only $1.78/lb. Walmart Grocery Pickup Butter is priced at $2.98/lb.
We go through about 4 lbs. of butter a month, making it perfect timing for my next Costco trip!

*Frugal Tip: Keep your yeast in the freezer to help it stay fresh longer.

7. Organic Extra Virgin Olive Oil
Another great buy at Costco is the organic extra virgin olive oil. You can buy a 2 liter bottle (which will last a very long time!) for only $9.45.

For only $11.49 you can get 4.5 lbs. of buttermilk Kodiak cake mix, which is much cheaper than at Walmart Grocery Pickup.

Many of Costco bulk spices are much cheaper than you will find at most grocery stores. One of my favorites is this this 20 oz. chili powder from Costco for only $5.49.
- Chili Powder at Costco: 27 cents/oz.
- Chili Powder at Walmart Grocery Pickup: 32 cents/oz.

- Mild Cheddar Cheese at Walmart Grocery Pickup: $4.22/lb.
12. 1% Low-fat Milk
I personally do not buy milk at Costco, but it can be a good deal for many people. My family are not huge milk drinkers, so we wouldn’t be able to drink the two gallons before it spoiled. If you go through a lot of milk and like 1% milk, than this is a good deal for you.
