neel, that depends on the way you setup a game. Could you mail me more details to puzzler[at]tradebit.com so I can take a look? Normally you would just add a preview to your game... that preview (like on the mp3s) is a timely restricted trial version and for the sale you add a serial key.

tradebit supports adding a serial key from a list to a sale. would that be working for your kind of games?
