Re:Costco is coming to Knoxville
When they open you can take a look around without buying the membership. I suggest that, then consider how much you would use the membership vs what you spend at the regular markets.
The regular membership is $50 /year and the business membership is $100. While we tend to be small consumers, the Business membership offers a cash rebate on purchases, and we have found that we spend enough to get an annual check of well over $200 which not only covers the membership fee, but is a nice spending boost for some of the experimenting we do with Costco Food products.
