I deal on E-Bay all the time, but-I only pay with money orders. Probably still traceable, but they’d really have to work for it.
They ship, right? And I don't think it would be at all difficult to trace the address where the money order was issued. PayPal might be a little more difficult.
Most pay Pay sellers are gonne be too much hassle to try to collect. But why should an eBay seller not collect the same sales tax that a local pawn shop selling the same used goods would?
