GreenDimes 
My 2cents: I'm not Al Gore or anything, but I'm getting greener.
This AMAZING website allows you to get rid of all that annoying junk mail that's killing our trees. I was skeptical at first, but now my beautiful empty mailbox is proof GreenDimes to the rescue. They even plant a tree in your name every month. I love trees! Here's the catch...it costs approximately $15 a year... less than a dime a day...thus the name Green Dimes. (Note: it used to be $36 a year.) Believe me, it's well worth it, and you'll feel a little greener when you get your mail, err, when you don't get junk mail! Note: it takes a few months to see the results...be patient.
