Best strategy for marketing e-books??

[John21]

Anyone have experience marketing e-books? I have a small publishing company with a few 'how to' titles that I'd like to market as e-books.

I'd like to avoid an adwords campaign, and just focus on affiliate links if that's feasible. I've been looking at clickbank, because of the affiliate possibilities - but I just don't know what I don't know.

Any help or advice is appreciated.
