Almost every dispensary in Colorado has some sort of promotion or daily deal that promises you a sweet price on eighths, grams of wax, pre-rolled joints and so on — but none of them have been as clever as the promo by the Grass Station and Oskar Blues. Shortly after the release of Oskar Blues' Pinner Session IPA — an IPA with a pot-inspired name, full hop flavor and less alcohol than usual — the Grass Station began offering one-cent pinner joints to customers who brought in an empty can of the beer, which just happened to have "Sip. Sip. Give." on its label. The pinner-for-a-Pinner deal didn't last long, but it will forever stay in our memory as yet another ingenious marketing strategy by the Longmont brewery.
