I sold an RCA tube amplifier to a buyer in Korea. It was sold through the Global Shipping Program and I shipped it to their address in Kentucky. Later they said the transaction couldn't be completed and refunded all money. I've sold tube amps to Korea before, non GSP, and never had any problems. Now I see my amplifier is back on eBay and is being sold by some guy in Michigan. He even uses the same photos and description. Does this make any sense to anyone?
