Many do. For one thing, sellers are unable to gauge the interest in ongoing auctions because last-minute bidders are delaying their bids until the flurry of bids at very last moment. For another thing, last minute bidding often forces sellers to sell items for less than what they would like. There is nothing a seller likes more than to see a several day long bidding war at the expense of several bidders. In the early days, sellers unsuccessfully lobbied eBay to prohibit last minute bidding. Some sellers understand that while BidRobot may keep the prices of items down, it also attracts last-minute bidders who might not otherwise bid for an item. Whether sellers like it or not, last minute bidding wins more auctions and is here to stay.
