Can't beat that I guess...
Maybe eBay should offer negative starting prices to persuade people to take hard-to-shift items, ie someone lists their ancient Mac for, say -$50, meaning that they pay the winning bidder $50 to take it off their hands, but then if two or more people are interested then they bid against each other to get the Mac for less money ie the winning bid might only be -$10 if one of the bidders is willing to take it for just $10 payment. Then if it turns out that actually there's a lot of interest in it, the bidding can go up into positive figures where you have to pay the seller to get the item instead.
