40 of the Worst Products to Buy at Costco

[adiqted_pagination]

So many products at Costco seem like a good idea, but then you get home and wonder what on Earth you’re going to do with them. There’s nothing wrong with the items per se. It’s just that there are often better ways to spend your money. Some of the items can be very unhealthy while others simply come in quantities that are too large for many households. 

Before you find yourself strolling through Costco thinking, “I’m sure it won’t hurt to stock up,” we want to share with you some of the bulk products that are unhealthy or not worth your money. They may be cheap and convenient, but these items take up a lot of space and might even cost you more in the long run. By the end of the article, you’ll have all the inside information you need to make better decisions next time you go to Costco.  

Bread and Pastry Products

Let’s start with some breakfast favorites – bread and pastries. Some shoppers in Costco love to buy bread in bulk to save money per unit. However, if you only have two to three members in your household, buying in a small retail store is still best. 

Bread only lasts a few days, so when you buy in bulk, there’s a tendency for this product to get stale or moldy before you can consume it. Having large quantities can also push you into overeating, which can contribute to obesity, heart disease, and diabetes.

Mayonnaise and Other Condiments

While the thought of saving money is exciting, you still need to consider the longevity of the products. Buying gallons or boxes of mayonnaise is not a wise choice.  Why? Store-bought mayonnaise only lasts a month if unopened. 

Unless you have a large, mayonnaise-loving family, these huge jars are likely to expire before you can get even halfway through. Furthermore, eating too much mayonnaise can lead to health problems such as high blood pressure and a rise in blood sugar. If you want to gain some weight, eating mayonnaise every day can help you!
