Hey CP you might have the germ of a good idea here....
How about this for an idea:
Cards for Kids
Donate your used gift cards with leftover amounts to charity. They are easy to mail and most people never use those last few $$ anyway.... but if you add them up, it could come to some nifty amounts for books, equipment or lot's of double-shot espressos to keep the kiddies awake...
Ya wanna register a non-profit?
