Is Walmart a Better Deal Than Costco? A Detailed Comparison

Costco and Walmart may not have the same shopping experience, but they both help you save money on groceries. How much? That depends on what you plan on buying.

Remember, Costco is primarily a bulk-shopping experience, whereas Walmart is not. For the products that follow, we'll compare per-unit costs when the amounts per package vary by store.

Check out some of these products at both Costco and Walmart to see which will save you money.

Editor's note: We gathered prices from locations in Utah or South Carolina (depending on availability), the states whose grocery prices were closest to the national average in 2022. Prices are subject to change and may vary by location.

First, let's compare Costco's 24 Kirkland Signature Organic Eggs and Walmart's 12 Marketside Organic Cage Free Large Brown Eggs.

Costco: $8.18 ($4.09 per dozen)

Walmart: $4.17

Winner: Costco wins this by 5 cents. This is a good example of why it's important to compare per-unit costs instead of overall prices.

Now, we'll compare Costco's 45-count container of 1-ounce Goldfish cracker packs with Walmart's 12-count container.

Costco: $14.99 (33 cents per pack)

Walmart: $6.73 ($2.24 per pound)

If you're trying to save money when shopping for essentials, make sure to compare per-unit costs when deciding between Costco or Walmart.

While you'll have to read the fine print, remember to compare per-unit costs. Sometimes a Costco membership will save you much more cash, and other times it's worth it to buy things individually at Walmart.
