I've given up on using ebay for most things.
I sold a tascam on there and the winning bidder didn't pay me AGES, then as soon as they did pay started a dispute saying I hadn't sent the item... So I posted the item as soon as they paid, then I get no emails about the tascam and the dispute is escalated to a claim... apparently I didn't describe the tascam as 'broken' in the add, and I sent a broken tascam... which is a lie! Paypal/Ebay said I had to refund the bidder and asked them to send back the item. I got a different tascam back with a broken PSU. I searched like CRAZY to prove it was a different unit but I couldn't.
So I lost my money, and gained a dodgy tascam.
I strongly considered going to the winning bidders house to brick their windows.
