Save Your Money: 14 Things You Must Avoid Purchasing at Costco

My family and I have been shopping at Costco for decades. We do much of our grocery shopping in the store, and many of the long-term employees know our children by name. However, we also know that not every item is a good deal at the membership store. These are 14 items we don’t put in our cart at Costco, and opt to get elsewhere.

Office Supplies

Office supplies don’t tend to expire, so you might think you’re fine purchasing them at Costco. Unfortunately, the pricing is fairly expensive on office supplies at Costco.

You’re often better served at buying such items at Walmart and Target.

Over-the-Counter Drugs

Costco sells a significant amount of over-the-counter medications. This can be a great way for a large family to save money.

Unfortunately, you must typically buy them in bulk. Not only can they lose effectiveness over time, they expire. Unless someone in your family regularly uses an OTC medication, you’re better off buying it at Walgreens or Walmart.

Paper Products

Do you really need 12 massive rolls of paper towels at once? You likely don’t. Grocery stores often run name brand paper towels as a loss leader, allowing you to save more.

Additionally, tests show that Kirkland paper towels often don’t perform as well as well-known brands. There’s no need to spend more for something that’s not going to be a quicker picker upper.

Ground Coffee

Lots of coffee sounds great if you love a cup of joe. But, as any coffee-lover will tell you, coffee loses taste and effectiveness once ground.

You can still buy beans in bulk at Costco, just invest in an affordable grinder from Amazon or Walmart.

Pre-Cut Fruits and Vegetables

If you have a large family, you know that buying produce at Costco can be a fantastic way to save money on groceries. That’s not necessarily the case with pre-cut produce.

We’ve experienced less than fresh produce in these offerings numerous times. Reports also indicate other shoppers having a similar experience. While convenient, it may not be worth the savings for you.

Spices

Costco usually has fantastic deals on spices. Unfortunately, they don’t carry a lot of spices. Worse yet, they’re only available in bulk.

Spices, like coffee, lose flavor over time. Unless it’s a spice you use on the regular, you’re better served by purchasing a smaller version at your local grocery store.

Electronics

Costco has a great selection of electronics. Unfortunately, the device in question may not have everything you want.

Companies often work with warehouse clubs to offer customers devices that don’t have all the features you will find from other stores. Or, it’s an out-of-date device. It’s part of how they keep costs low. Before purchasing electronics from Costco, comparison shop to ensure it’s what you want.

Mattresses

A good mattress is a necessity. Costco offers great deals on mattresses, but they lack selection.

You are typically better served by going through a local retailer, especially if you can purchase your new bed on a promotion.

Cooking Oil

Unless you fry food a lot, that massive jug of cooking oil isn’t a good deal. Oil goes bad, and can even turn sour or bitter.

Buy a smaller version at your local grocery store and use a receipt scanning app to reduce your cost.

Books

Avid readers know Costco often isn’t the best place to purchase a book. They typically don’t have the latest best seller and you may get a better price at Amazon or Walmart.

Better yet, use your local library to completely reduce costs.

New to You Products

Don’t let FOMO trick you. If an item is new to you, it’s usually best to avoid buying it in bulk at Costco. The last thing you want is to be stuck with a lot of something you don’t like.

Instead, buy it in a smaller quantity at the grocery store to see if you like the new item before making an investment.

Flour

Believe it or not, but flour has an expiration date. Worse yet, flour attracts moisture even if you seal it tightly. That 25 pound bag of floor often only lasts about a year. Whole wheat flour can go bad in several months.

Unless you’re a serious baker, it’s best to avoid buying that large bag of flour at Costco as you may end up losing cash in the long run.

Glasses

One helpful feature of Costco is their optical department. You can get an affordable eye exam, but look elsewhere for your new set of frames.

There are better choices to buy cheap glasses online to cut costs and get a better selection.

Soda

Costco may offer good deals on soda, but you must purchase it in bulk. Grocery stores often sell soda as a loss leader, and if you use a coupon app you can save even more.
