I just signed on with this program and have already made some income. They have a free members area that has some good information and if you find it useful you can choose to upgrade the membership for the additional information and tools they provide. I've had some success with the getting some new Ebay sign-ups through craigslist postings. You can check it out and see if it's for you here: Auction Affiliates
Excuse moi, does eBay has an affiliate program? I though it was only meant to sell stuff, but if it pays via Paypal I would like to learn more about this please.
It's called the Ebay Partner Network. They used to do it through Commission Junction but now handle it exclusively on their own. You get commissions not just for signing up new ebay members but also for helping other sellers get winning bids on their auctions. The link I listed will discuss some of this and also offer suggestions on how to take advantage of the EPN affiliate program.
