We have the Costco Executive membership plus credit card. We just got our rebate check of $349, so paid for the membership plus some. We buy all our gas there, which has averaged about 15 cents cheaper that prices nearby. Food quality and prices are better than local supermarkets, so we buy 75% of our groceries there. I guess we would only consider dropping it is if we moved somewhere where the Costco was more than 100 miles away....but then we would never move that far from a Costco!
