This free $20 American Spirit gift certificate has been around for a while, but I only recently came across it. It's like discovering a brilliant TV show during its third season. The only difference is one kills you through lung cancer and the other though heart disease. Tomatoes, tamatoes!
There was also an ad in Esquire with a promo code of SPIRIT, but I haven't the slightest what additional freebie (if any) this might trigger.
