As jayce said how can using escrow reveal your identity? You don't need to provide any information to the escrow. All that the escrow will do is hold the funds till the buyer receive product and then send the funds to your wallet.
What if user declines to buy it when it under the custody of the member holding them ?
I will have to revel my address to get'em back.
I have seen such a case not in escrow but i am avoiding it at all the cost .
So i will stay quite on all those replies who say escrow or something related to it.
Edit: Well you can use a no return policy in that case the escrow will release the funds as soon as the buyer gets the products
