I've been a member since '07 but I didn't pay attention to their affiliate thing or even check my account. I have a couple of celeb blogs from my country and didn't know that I already sold some mp3s LOL Anyway, recently I put up some site with some amazon products and viola 4 sales in two weeks. Sux but it's fine. LOL I'm still learning and hoping for the best. Cool thing is that I used to work at Amazon HQ as temp when I migrated 2 years ago. I'm now in Cali Way to go...
Just pick a product ang promote it as best as you can. So far I'm not good with it. I'm just too busy with my real job. I can only update sites every weekend.
