I have been with gkworld for about 2 years and they have never been late on a payment. Sorry about the link: Gkworld That should work. As far as smartpricing goes I think I have been too. My clicks are like 2-4 cents at adsense. I switched to ypn and it helped a lot even with their much smaller inventory and way less click throughs. I am looking for more small affiliate programs. They pay more. There may be some risk but I typically do enough research to know if it is a small risk/reward ratio or a large one. Just do a search for sites running the affiliate program in question and email the webmaster or owner. GL!
I love, love, love AffiliateFuel.com They and their whole operation is so professional and fantastic. I'm biased - yup, - I've been making money with them forever. Give them a try.
