But... There is a different kind of scam which is much worse.
Scammer buys the item. Then opens a case with ebay saying the item is broken or not as described.
You are required to tell the buyer to send it back for a refund.
The buyer mails you back an empty box.
Ebay still forces you to refund the money.
A friend sold a phone system. They said it didn't work. But what got returned was a different phone system broken.
They lost because they didn't have enough evidence to prove a swap was done.
