To follow up on Bemac's scam report, there looks to be a new scam around on Ebay. Not quite sure about the exact details on how it works, but I can tell you that it ended up with Paypal/Ebay refunding me directly after they got tricked into closing the case WITHOUT seller actually refunding ....
Here is the item in discussion, the seller looks like a real sweetheart, the negs keep on piling

1. Immediately after purchase he refunded me $1 - it seemed weird but, aw well, I am not complaining about a discount ... The refund goes through fine

2. Then few days after he tells me that he would not ship the coin (it was lost/stolen/the dog ate it) so I should file a dispute for not received to get my money back. Done ...

3. He then allegedly refunds me the $759 balance and Ebay/Paypal closes the dispute; but he does not have enough money in Paypal or he refunded via e-check and cancelled ASAP (Ebay/Paypal CSRs gave me contradictory info here), so the money never gets refunded. But the case is still closed so I am SOL



Looks like the $1 partial refund that WENT through was the key, the Ebay/Paypal system sees that one first and does not look at the refund for the balance - pretty nasty loophole

4. I get mad and call Ebay/Paypal, get them into looking at this so they refund me directly (I still keep the Ebay bucks, plus a courtesy coupon

)
So guys, Caveat emptor!
