Bottom line

Kevin Brine/Adobe costco wholesale corporation

Costco can be a great option if you’re trying to save money by buying in bulk, but a Costco run can be pricier than your typical trip to a grocery store.

Check your wallet for the best cash back credit cards when you head to Costco so you can save more while shopping.

It’s also a good idea to take a shopping list and stick with it if you’re worried about staying within your budget the next time you visit Costco.
