We joined Costco about a year ago. We have definitely enjoyed buying things in bulk that we use often, like chicken and toilet paper, so we don't have to shop quite as often. While it isn't always cheaper to buy in bulk, Costco occasionally sends out coupon books that make the deals almost irresitible. The Costco in Durham aslo has a gas station which is consistently the cheapest around, especially for premium gas, which my car requires. If you go on the weekends, there are lots of delicious samples that can basically make a whole meal (for me anyways). I am a bit dissapointed that they have increased the annual fee yet again. Overall the store is clean and worth a visit.
