Worst: Hummus
Unless you plan on throwing a party, you won’t need as much hummus as a Costco-sized tub will give you. Get a smaller sized container from a traditional grocery store in order to prevent food waste.
Worst: Printer Paper
If you don’t print a lot at home or if you’re shopping for your office, office supply stores usually have better deals on paper than Costco. You can find paper and supplies for rock-bottom prices at stores like Staples with good coupons or during back-to-school time.
