This was asked and answered here in the thread about the 37Signals article: http://news.ycombinator.com/item?id=616948 http://news.ycombinator.com/item?id=616948 eBay has an affiliate program called the eBay Partner Network (http://ebaypartnernetwork.com http://ebaypartnernetwork.com), and so CarsForAGrand will make money when somebody clicks through and bids on one of the listings, or even if they click through and bid on something else in the next couple of days and still have the affiliate cookie.
