Seafood
Costco draws a lot of customers in who are looking for deals on food items, but not every food offered at the store is sold at a low price. Items like seafood, which can include salmon filets, shrimp and even lobster, are usually sold in bulk at the store. So while you’re getting a good deal on good quality seafood, you’ll have to buy a lot more of it than you typically would to get those savings. But if you’re the kind of person who loves seafood, this may be a good option for you and your family.
