When I first signed up on eBay, I found an item I wanted, and had a "bidding" war and eventually one the auction. But as I've been on eBay for roughly 10 years now, I've learned to "watch" items, and only bid in the last few minutes.
I guess people might be like me in the beginning and think their high bid with 4 days left might be the high bid, but doesn't it seem silly to bid on an item with days left to only continue to raise the price?
I've watching the lenses on ebay and they have days left and the prices have gone up a few hundred dollars already.
