But you can save more at Costco than just dollars. We did the search and found some of the best insider shopping secrets, from what the asterisk means on the price tags to its discounting schemes and non-member hookups. Intrigued?

Even if your friends don't have a membership, you can invite your fellow scrooge sisters on a shopping trip via the Costco Cash Card. You have to be a member to purchase the card or reload it with money, but with this handy plastic, your friends can shop at any Costco location, including online. They could even put it toward their own membership—now that's savvy.
