I like Sam's Club more than Costco, truthbetold (though they are basically the same store with different names and that same warehouse lighting). This Sam's is so clean, and I feel like I'm in a secret club every time I walk in with my mom's card.
And it's amazing all the things one could convince oneself one needs when one doesn't actually need more than one of said thing. Like, I almost bought 6 electric toothbrush heads, just 'cause.
There's also a little cafe thingy that sells pizza, hotdogs, etc etc, for grotesquely cheap prices. If you can stomach it, get yourself a $1.50 hotdog and an 87 cent GIANORMOUS Coke. In this economy, that's the kind of deals I only wish we had in DC.
