Tried Amazon Associates and Bombed out

I've been using Amazon Associates since 2001. I won't lie to you though, I haven't earned much from them. Before anyone asks I've only made between $50-100.00 from them. I know others have stated they get that a month. Got any secrets? How about another program that offers this same type of stuff? I'm always eager to try things.In the next few days I'll mention those things that worked for me
