Ebay Partner Network.  Did around the blog on this site and I will talk about it.  It can be good for some people, and not for others.  It's finicky…I was almost at $1,000 in earnings per month and they dumped me.  Back in the day (2008 and 2009), they were screwing Affiliates quite a bit.  Maybe this has changed since then as they moved to paying for clicks rather than commissions on products sold.  When it was commission, it was awesome.  I had 1 sale once that was $44 in commission!  With clicks, it's like Adsense…and apparently now they really focus on quality websites and traffic.

It's something to look into if you already have a website with some traffic, as I'm not sure they will approve people now with new or mediocre websites.  I still have my account but don't do anything with it right now.  I might soon, if I can find the right niche.
