My coffee habit makes Costco pay off for me. The store near me has a roaster and the Colombia Supremo beans are enough cheaper than other readily available sources to cover the cost of a basic membership with a year's worth of coffee beans.
Fuel is relatively inexpensive, certain other products are good quality and price. Dog treats, Tillamook sharp cheddar, wines, toilet paper, etc. they've had competitive offerings on the last few sets of tires for the cars as well.
