Let's say there are two people looking to buy a certain video card in a certain eBay auction, Bob and a guy named Fred.
Bob and Fred are both willing to pay $100 for the card. The auction is at $50 with no bids.
Scenario 1: Fred, the inexperienced eBayer who likes to overpay, quickly spots the auction and bids $100 so he'll be done with it. Minutes before the auction ends the price is still $50. Fred thinks he's going to get the video card for $50. Now it's Bob's turn to try and snipe. He bids first $60, then $70, then $80, then $90, then $100 but still doesn't have the card. Bob gives up and Fred wins the card for his maximum price $100.
Scenario 2: Both buyers silently watch the auction that remains with no bids until the last few minutes. Both are unaware that someone else is trying to get this item so with 20 seconds left, Bob bids the minimum $50 on the auction, assuming no one else is going to bid. Fred, with his fast reliable cable connection, quickly notices this bid with only 15 seconds left. With only one chance at bidding, Fred bids $100 (like he did in the last auction). He gets his bid in with 5 seconds left and is in the leading bidder with a cost of $51. Bob has no time to react and Fred wins teh video card for $51.
LOLOLOL those scenarios are so biased. You're ASSUMING the guy on the other side is on a slow connection, but what if he was on a fast connection? What if there were 3 others bidding as well? LOL You're second scenario is so biased. You're assuming that Bob the idiot bids only $50 on the item he wants at the last 30 second, and then you're assuming that Bob is on a slow connection and doesn't catch Fred bid of $100, so Fred wins at 51. But take out either of those assumptions, and the results is the same as Scenario 1. If Bob bidded at $100 at the last 30sec before Fred, Fred is SOL. Or if Bob did bid at $50, and Fred outbidded at $100 and is leading at $51, but Bob connection is fast and catches the error, and ups it to $110 and wins it for $101. Fred is SOL again.
Well, if it makes you feel better to think bidding at the last 30 secs really is going to give you a better deal, go ahead and set aside that time and refresh the screen continuously while you put in your bid, HOPING the other person puts in a low opening bid, HOPING the other person is on a slower connection, and HOPING you don't get multiple last second bidders. That's a lot of hoping. Me, i'll rather proxy bid and forget, checking my email to see if i win or lose.
