I'm unclear on how escrow would work here. You're selling a preorder, so there's nothing to inspect and approve release. Were you going to wait for escrow approval until they ship?
The escrow service would be given the cointerra login name and password. The password and shipping address can then be altered so that I can no longer access it along with the e-mail address. This can all be altered again by the buyer.
I was going to just hold onto this, but I'll let the bids keep going..
