By far the best of the wholesale clubs. They have the nicest and best quality food items and the Costco brand "Kirkland Signature" items are just as good as any name brand in my experience so far. When gas prices were out of control their gas was a great deal too but now that they have come way down they aren't generally a great deal cheaper than other area gas stations, on occasion it might even be more. While I have not myself had to return anything those who I know have say that Costco is very flexible about returns and their customer service is excellent. If you can only join one wholesale club make it this one.
