What do you think of "Earth Class Mail"?

I currently rent a P.O. Box for 1) some level of abstraction/anonymity for online transactions and 2) to have a permanent address in case I have to move. I also use PayTrust to receive all my paper bills and feel that it is well worth the cost.

I pay at least $40/year for a PO Box and its often a hassle to go and check mail—if I don’t do it often enough, the Post Office locks up the box and starts returning mail to senders.

I am now moving from one state to another and am wondering if I should move all my mail online using Earth Class Mail. Just as I never miss a bill and never have to deal with paper bills (because of Paytrust), Earth Class Mail could potentially do the same with all my paper mail.

What do you think of this service? Has anyone used it? Do you feel its worth it to pay $10/month for someone to open my mail and process it electronically?
