Why do eBayers drive prices.

[The Russian Bear]

Seriously why do people insist on having a bidding war days before the product is due to finish? Take this for example, Witcher 2 CE sealed which has over 4 days until the auction finishes but it is already at £82 and had a starting price of 99p no reserve.

Why can't people wait until towards the end of the auction to bid instead so that the prices stay reasonable. I mean i got the Shogun 2 CE for £31 thanks to everyone bidding on it in the last minute.
