The internet version of the "Golden Ticket"
Very interesting campaign from Hershey's & Ebay where you collect codes from wrappers to bid on items on ebay. Will have to check out if it pings the lameness meter, but the concept here is a great one. Having been a fan of the Pepsi iTunes promo (especially since you could "hack" the bottles and win every time) this should be interesting to play with.
