I honestly don't even think using escrow would be safe for the buyer on this one. The OP is likely going to say that he somehow the funds were not received or that whatever code was given to him did not work/was redeemed already ect.
I'd be perfectly happy to send CASH directly to the escrow provider. That way the escrow provider can count it and make sure it's all there. They can then forward that on to BTCist (I'll even provide the postage paid addressed envelope for forwarding it. That way the escrow provider can know with 100% certainty that I have provided the agreed funds.
That would work, however they would need to be US based (a lot of them are not - but I think TC is), and the escrow provider would need to reveal their identity/address/PO box to the buyer, which is something that a lot of escrow providers may not want to do (especially TC - a lot of scammers hate him, although he may trust you specifically with that info), as well would delay the time it would take the seller to receive funds (this is probably a necessary evil involved in using escrow though)
