I think you’re supposed to save money shopping at Costco. We’re definitely not.
In theory we should be saving money, buying bulk laundry detergent, paper towels, and eggs at these fantastic prices. It’s just, well, all of that other stuff.
An impulse buy at Costco looks like this:
Not one box of macaroni and cheese, but TWELVE.
Sometimes an impulse buy will get you 12 chicken patty pita sandwiches you find you don’t actually want to eat more than two of. Other times you find a winner that you re-purchase time and again.
