I have been using slickdeals.net to find some of the best deals out there. This is an article that exposes some obscure state laws that allows people to buy alcohol for up to a 20% discount at those member-only stores like Costsco and Sam's Club WITHOUT having to be members. Although I am a member of costco, I love stickin to the man since, you can't buy booze in our costco anyway (gotta love PA liquor laws).
