Don’t Buy- Condiments
The good thing about condiments like Ketchup, Mustard, and Mayonnaise is that they can stay in good quality forever. However, as soon as you open them, they need to be put in the refrigerator so just keep that in mind.
Don’t Buy- Salsa
Costco tends to have large quantities of food, and this salsa jar is surely a party size. The large quantity makes it perfect for a big group of people, but it also may go bad, so if you’re not a large group of people, then it’s best to get a smaller container.
