greendimes.com

what a nice idea. even though you could probably stop a lot of your junk mail through your own efforts (and for less that the amount this site wants to imagine it would cost you), greendimes.com seems to offer a nice service. for $36/year they will reduce your junk mail, protect your identity (by reducing the number of credit card offers that come your way), and plant a tree each month. seems like a decent deal to me. might be a nice gift idea, too.
