I've made a ton of money from eBay over the years since joining them in 2008. My best month was over 25k in earnings which was a few years ago.
Then, when Goog wacked a lot of affiliate sites it dropped a lot. It still paid the mortgage and I didn't have to do a lot with it.
Then OCT 1st rolled around and the new payment structure kicked in and I'll be lucky if I earn enough to go out to dinner this month even though I'm sending the same amount of targeted traffic. By the end of the month, I will have removed eBay from all my sites. I refuse to send them free traffic.
Going to a 1 day cookie killed it for me as well as many others.
