Do your grocery shopping elsewhere
While it might be tempting to take advantage of a warehouse club's marked-down prices on produce and meat, buying your groceries in bulk makes sense only when you have a big family or lots of freezer space. You'll end up wasting a lot of food (and money!) on produce you're unable to eat before it goes bad.
Instead, hit up your local grocery store and take of advantage of their daily deals and discounts, and use your warehouse club membership to stock up on nonperishables.
