I just keep it. The only thing I ever really get is address labels though. I don't donate to larger organizations anymore - I feel too much is sent on advertising and sending out crap like that, not where it really needs to go. I donate to local rescue groups only. I donate a portion of my pet portrait profits to the local arctic breed rescue and the store I work at raises money each year for several foundations that I donate to. I really only donate to pet related things that's probably bad but it's the truth.
