Has this paid out well, in your experience? Or would you recommend eBay's system instead, if one had to choose.

My preferred scenario is a CPM system, but alternately I believe as i set up this site if I find the right sales keywords I might get some click through compensations (I guess this would be the CPS system: people clicking the ad and purchasing the product featured).

For me, I believe that Amazon is a better programme. But it's going to depend on your niche, surely?

I used to have an Amazon link on my blog site and for a while I did really well from it - because one particular friend of mine did all his shopping through my link and earned me quite a few vouchers! Problem with Amazon though is that you end up buying books and CDs rather than paying the bills.

I think Amazon is great, as long as you have a good niche with great traffic.
