If you want some free binaca, you can get a coupon for one free product via snail mail by signing up on their site. You have to click on steps one and two before the signup form appears under step three and you'll also have to confirm your email. The coupon should be good at all Walgreens and Wal-Marts but it might also work at additional stores.
On a related note, can anybody else think of binaca without simultaneously thinking of Jim Carrey talking with his butt in Ace Ventura? If so, kudos to you.
