Anyone here use Amazon affiliates as a monetization method? Anyone use them in the past and not like them?

I love Amazon.... I pretty much use them exclusively.... I've made $10,000+ this quarter (Oct, Nov, and half of Dec.)... granted, it is the holiday season, but I have a pretty good year-round niche, that just happens to do well during the holidays. Most of that money, probably 90%+, is from 1 site... the rest of the sites just do a tiny amount.
