Amazon Affiliate

Yesterday I received an e-mail from somebody offering me to be an Amazon Affiliate. I did read about joining 'Affiliate' to get cash through advertising.In this case , I can advertise Amazon 'business'in my blog. If anybody click or order things from the advertisement,I will be paid by the company.Though, it seems positive, I do not know how to manage it (lack of knowledge again!). If I know how to go about it, I would certainly advertise on selling books especially books on craft, embroidery, quilting, sewing, patchwork,crocheting and so forth.I think many ladies overthere who are intersted to buy those books including me.And I also will get money without working !..anyway..That's only my sweet dream eh?
