All that it really takes to see a price like that is 2 people willing to spend a couple hundred. You gave yourself the mental ok to spend $200, but you were so excited about winning you just had to snag it from the guy who out bid you. It's only $10 more. Big Deal. On the other end, He waits a couple minutes mulling it over but ultimately decides what the hay. All of a sudden you look up and you just bid $400 for a razor.

I would never do it, but I know how it happens. You get so worked up about winning, you forget you are overpaying.
