Thought this was fun.

There was a card for auction with a BIN that I was willing to pay. But I was also feeling cheap and thought I'd try to win it in the auction and save a few bucks. Auction ended late at night, so I went to set a snipe rather than stay up late. But I realized that once you've decided that you're not going to hit the BIN, that it has a BIN is irrelevant to your decision. The rational thing to do is to just bid whatever you're willing to pay for the card. So I put in my snipe above the BIN price. I figured that I would win it for less than that, but if I'm not going to use the buy-it-now option, it doesn't make sense to bid less than what it's worth to me.

Anyways, I woke up the next morning to find that I'd won the card for a nickel above the BIN price. I suspect that the underbidder and seller woke up the next morning and were confused.

And being cheap cost me a nickel.
