You need to do a lot of “homework” and research before spending money on PPC to drive traffic to affiliate merchants.
If you’re thinking about buying a “program” that some promoter is selling, think twice.
I’ve written an article explaining why most people do NOT make money from this strategy. See (no ads, just advice).
A good place to research affiliate marketing is ABestWeb (http://www.ABestWeb.com/) which is a community of affiliates and merchants — don’t post there until you’ve spent at least 10 hours searching and reading old discussions.

I’ve not come across one merchant who would allow you to bid on their brand name using PPC to simply drive traffic to their site they would have got anyway. Few even allow you to bid even on generic keywords with the sole purpose of sending traffic directly to them. The point of an affiliate program is for sites to place banners/ links on a site that drives traffic the merchant wouldn’t normally get, thus expanding their reach.
In fact Google band advertisers from doing this

Why would you devote your time, money and energy to attracting prospective customers from your target market niche without first finding out who they are before you decide to make your affiliate offer to them?
