Don’t Buy- Ground Coffee
If you live, eat, breathe coffee, and can’t function for the day unless consumption of coffee was made, then you are one of us! Although you can save a lot of money with a bigger size of ground coffee from Costco, it certainly does not make up for the loss of quality in taste. When the coffee beans are grounded and exposed to air, they will immediately lose their flavor and intensity.

Buy- Gas
Costco gas is a necessity on this list as it is something that all of us need, most notably if you are a member. The gas prices are unbeatable, which is why having a Costco card will help a LOT! Even if all the Costco stores close, getting a membership will still be worth it as long as their gas stations exist. You definitely would not like paying more for gas that you could have bought with less price, right?
