Buy: Peanut Butter
We are sure that at least one person in your household is a big fan of peanut butter. This is the reason you should always have a big jar on hand! When you buy it from Costco, you can ensure that there will never be a lack of peanut butter in the house. You no longer need to worry about hiding your jar from your roommates. This is also true for almond butter if you like that more than peanut butter.
Buy: Bagel
The Costco bagels are in a league of their own in our books. When you go to the warehouse store, you should get them because they go well with cream cheese, salmon, and whatever you have in mind. They are sold in twos, and you can pick the flavors that you want. You do not need to worry if you do not finish them in one week. After all, you can just freeze the leftovers and heat them up later on.
