Dude, that's called Capitalism: Buy low, sell high. My salary got cut by 30% because of the Wuflu, so I think it was justified. I have many more transactions on this site at fair prices. Those just happened to be in short supply.
Gunbroker is even worse. I sold a TAC-13 on there for $1500 in this panic, all newbies bidding on it. First one to win it just flat out refused the terms, got threatening, and got himself kicked off the site, second one also a newbie, completed the deal after a lot of hand-holding.
