Mike Kohn sat anxiously by his computer as the clock ticked down on his eBay auction.
With hopes of catching a last-minute buyer in a desperate bid for Sony's latest hardware, the PlayStation 3, Kohn listed the gaming console a week before Christmas.
But as with many Internet auction sellers, Kohn learned demand for the system was not what he anticipated it to be.
"Waiting was the mistake," he said.
A study by gaming Web site Kotaku.com tracked the average sale price of the PlayStation 3 on eBay.
After a peak of $2,367 on Nov. 15, the average ending price plummeted to $800 by Nov. 26. The lowest average was recorded Dec. 21 with the systems ending at $724.
