Costco has great vodka. I seem to recall that there are two varieties. One is supposed to basically be Grey Goose and the other is a premium American vodka, but I'm not sure what the original label is that they're rebranding.

I buy maybe 3 things at Costco: Vodka, Prime cuts of beef (can't find these easily elsewhere) and bulk packages of vacuum sealer bags for fishing season.
