No offence, but what do you think real world business is? Real estate, stock market, etc. Buy low, sell high. It's essentially flipping. Passing some kind of moral judgment and thumbing your nose at people for it is stupid. Sometimes you're in the right place at the right time, and sometimes you're not. That's life.
And I say this as somebody who got BestBuy to price match Target's $59.99 price for the CE back in October. I opened it up, enjoyed the hell out of the game, and have no intent to sell it. But I'm not going to cry about people seeing an opportunity in a dry market.
