Folgers Ground Coffee – Don’t Buy
In most instances, buying in bulk is the best idea but not when it comes to coffee as once the coffee is grounded, the beans lose their flavor and strength. So skip the big jar and get your coffee elsewhere.
Gas – Buy
Even if Costco didn’t have warehouses that sell household items and all they sold was gas, you would still save if you have a membership. Whether you drive a lot just remember to take your membership card with you next time you fill-up.
