Ebay Fever: Also known as "auction fever" or "competitive fever" or "decorate your home for Christmas contests". When getting what you want, or winning a contest, becomes more important than the contest itself, and the cost/value considerations no longer become the primary consideration.
I recently was looking at some toys on Ebay for the kids -- Transformers, to be precise. Not the new ones, but older ones from the early 80's when I was a kid. I got the old cartoon show from that Era for them, and they love it. I was bidding on a lot of I think 10 toys. They were in well played with condition, and the bid was very reasonable. So I started bidding. Then another guy decided at the last 15 minutes he had to have them. There were no rares in this lot. It was average, common, units. They were in very played with shape (perfect for kids to use). Then a 3rd guy hops in -- I took it about twice what I originally intended to pay at the most (double my original stopping point) in the heat of the bidding before coming to my senses and dropping out. I had been pricing them for a while, and knew what they were going for. I would have very much overpaid. They finally sold for 4 times what I ended my bidding at! (Proportionately, their "value" bid was $25, maximum value $50, I stopped at $100, and they sold for $400. Not kidding. Got a better lot for $30 bucks that same day.)
Whenever there is a bidding war, particularly among rivals for something they know the "opposition" wants, then you end up with an ending value ridiculously above market price. #22, #61 and a conditional 2nd or 3rd that could be a first next year if Roy performs (which you know he likely will)? How much will Jerry Jones, or the Eagles, or KC Pony-up to keep division rivals from getting a WR they want to have, but don't want to defend twice a year? It could get into $400 territory -- and if it does, pro-bowler or no, against my wishes or not, everything has a price. If the E-Bay Fever takes over, some team may actually say yes to the Lions and pay $400 for something that's worth twenty five to fifty bucks.
For the record, I'm betting against it; but I never have been much of a gambler.
