Dang...on the one hand that's kindof some impressive and quick thinking...on the other hand, it kindof makes those people jerks for taking an unfair advantage or setting something up like that. I mean...the idea the one article mentions that fake sales were set up on Amazon for the PS4 thing, and the "get rich quick" idea behind buying a ton of something on an erroneous deal and selling it at regular price on ebay...those are annoying!
I don't ever find any deals either, although probably about 75% of the time I'm too lazy to search for them. :-P If I ever to look or stumble across something, I'll try to share it! (I can be pretty lazy though, so don't hold your breath! ;-D It'll much more likely be the stumbling than the looking!)
