6. Single-Item Offerings

Costco makes lots of money and gets savings on bulk purchases. The warehouse club buys large packages and cuts customers in on the savings. In other words, you should be skeptical of anything the store tries to sell you in single-item form.

This doesn’t apply to every product, however. Costco vacation packages and car deals are reliably less expensive than you would spend on the exact same item at a regular store.

That’s why the best thing you can do when seeing a single item offered at Costco is to use your mobile phone to compare prices elsewhere. It’s a great strategy to ensure it’s a really good deal.
