Good Sales Stratagy

Had a beer last night, quite a rare happening these days! This morning was about to put the bottle cap in the rubbish bin and saw this. The Brewers, Veltins, have a Prize Draw running, you can win anything from a VW Polo to a Crate of Beer. Instead of putting the winning numbers on the label, they are in the Bottle cap, Crafty! The print says, " Not a Winner,now open another and try again" Well thought out!
