I've been reading up on the whole CarsForAGrand.com thing a bit in the last couple of days. I also took a good look at the site.
Besides one Google ad box on the bottom of the left column, I cannot detect any other ways of monetization for the site.
Most of the sites talk about the author of the site as a person "earning a six figure salary thanks to the site."
What am I missing here?
eBay has an affiliate program called the eBay Partner Network (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.
