Seems legit to me. I feel quite a bit of pain that can be solved. I usually just don't sell stuff because it's quite the hassle to go out, get a box, ship the stuff at the post office etc.

If they can just solve that for some fee I'd be pretty happy already. Buyout from Ebay/Amazon is likely if this works.

Basically I'd like my workflow to be: Put stuff on Amazon/Ebay...when it's bought the postman will come the next day and pick it up and deliver it for me. Kind of like a reverse Amazon-Prime.
