I won a Shell fountain drink yesterday but haven't tried to use it yet.  Ummmm wouldn't most Shell minimarts have a soda machine?  It reminds me of the Subway one and the free chips.  I agree - the companies need to send a letter to all of their franchisees letting them know about these games.  Do the employees not see the signs plastered all over the windows promoting the game?

I think the frustrating thing about the Hawaiin Tropic and others that say you're a winner and then you're really not is all of the time invested in these.  I realize it's all part of sweeping, but it's discouraging when you make the effort and get excited only to find out that you didn't win (when it did, in fact, say you were a winner).
