Messageproducts.com has a variety of checkbooks and accessories everyone might be interested in. If you use checks, that is. They use recycled paper, soy-based inks, and have a variety of messages. They are a tad bit more expensive than some places I've seen online, but royalties are paid to the association/club you choose. They have a huge variety! Amnesty International, different humane societies, Vegan Action, PETA, NOW, PFLAG, the Sierra Club, and Greenpeace are just a small part. They also have hemp checkbook covers and clutches, solar calculators, etc. Check it out the next time you shop for checks.
I just thought this was fitting in this community. If not, I'll delete it.
