Neither I've enough hits/day which might suffice the criterion of affiliate marketing, nor do I love seeing banners clattering my "neat and clean" top space (or even side space for that matter). For my situation I would say affiliate marketing sucks!
I am getting two units of these plus two batteries. That's $170. Thanks to affiliate earnings, i can get it redeemed as gift certificates and now I am getting it almost for free. Its not free. The site did earn it. But its a gift card so...its "phree".
