Every week at work on Fridays we have casual day. You get to wear jeans for a $1. We pool all the money together and at the end of six months we donate all that money to a charity. In the next six months we will be donating all our $1's to the diabetic association. Every little bit helps.

That is awesome. You could also have a swapmeet of stuff and to participate is 1.00.
So how well ahve you guys done so far?
