I used them on a transaction and got royally screwed. After shipping the merchandise to the buyer signature signed, the buyer decide to return the merchandise a week later claiming damage. On the return, the buyer didn't send the merchandise back signature required (as was required IN WRITING at the time). As a result, this $1000 merchandise was delivered and left out on a porch in the rain!
But hey, never mind if a buyer doesn't comply with the agreed terms of the transaction,
To add insult to injury, I also never even received a check for a refund on my shipping from Escrow (which was also written as required). Not that it mattered on this loss.
Stay far away from this crooked company. They backpedal when confronted with policy violations and like others have said, it takes forever to get nothing resolved. They are mainly interested in their fee which is almost always paid for by the buyer - who you think they are going to side with?
I have had hundreds of transactions online and this was the worst experience ever. NEVER sell any item through them or you're asking for trouble.
