I am very happy to see that you not only sold it for market price, but also that doomy didn't get a chance to buy it and re-sell it stripped down to nothing for 3x market price.
Geee I wonder why he re-listed his A4000? Because he's dishonest and tried to inflate the shipping *or* he had someone he knew outbid so that he could make it look like these are actually selling for that price... in an attempt to inflate the market value.
