Can 41pounds.org Help Me Reclaim My Mailbox?

"The average adult receives 41 pounds of junk mail each year.  Our service stops 80-95% of unwanted catalogs and junk mail for you. We’ll contact dozens of companies on your behalf to stop your junk mail and protect the environment."  This is the claim made by 41pounds.org, a non-profit organization working to rid the earth of annoying and eco-unfriendly junk mail.  Junk mail is a recurring topic in our house.  We absolutely despise the circulars!  They're read every blue moon, but are most often tossed in the recycling bin as soon as they enter our home.  And it's not just annoying to us but also a huge environmental nuisance:

To produce and process 4 million tons of junk mail a year, 100 million trees are destroyed, 28 billion gallons of water is wasted, and energy equivalent to 2.8 million cars is spent...

I've never researched the proper channels to take to cancel unwanted junk mail, so I don't know how easy or difficult it is for one to do what 41pounds.org is offering.  But for a service that lasts for five years and cost $41, it may be worth it considering the organzation does ALL of the work for you.  They even send you stamped, pre-addressed postcards to send to companies that require a signature to be removed from mailing lists. 

So I'm gonna test this service out and see if the organization lives up to its claims.  I will even have more than 1/3 of the fee donated to a community or environmental organization.

Hoping to soon lighten the mail carrier's load,
