Either way you didnt understand or didnt want to understand what I said...
I said that your escrow service only protects the seller of the good as long as he has a receipt that he has sent something no matter what it was that he has sent. Could be a brick, could be the $1000 watch.
Taking your last stupid comment into consideration, you even allow now buyers to trick sellers:
If they couldn't reach an agreement then I would ask the buyer to ship the watch back to the seller at their own expense and once the seller receives the watch I would refund the coins back to the buyer.
So all the buyer has to do is to say, that he received a brick (while he got the $1000 watch), ship a brick back to the seller, show you the receipt and you give him his money back...
I mean who is trusting that kind of escrow here, I wouldnt accoring to what you wrote before... All you do is adding a little additional effort for the bad guy, while you have to deal with this crap...
If you want to do an escrow, then get the money and the goods, test the goods (give it to a jeweler in case of watches, or test it on your own if you can, like an HDD or GPU ...), charge something for your effort/expenses and forward the rest to the parties. Everything else is nonsense.
If thats still not clear for you, then Im sorry for you, anyway you wont see any further comments from me in this thread.
