Hi there. I wrote an ebook and sold it on clickbank for two years. I believe there was a $50 'approval' fee, and then they just took a small percentage agtrrthat- no monthly fees. They don't host your file - I did that on my own web server, and used a program called dlguard ($99 when I bought it) to securely deliver the ebook to my customer.

I did print on demand, and got on amazon for free. I'm not sure if they do it but lulu has a 'published by lulu' option where your ebook gets an isbn (required to sell a physical book most places) for free. Also, after a number of months you get put on a list that makes you available on amazon and from other major booksellers. This all cost me exactly $0. The lulu plan I would recommend also has no monthly fees, and they do take a higher percentage since they're actually printing a book for you.

Monthly fees are a killer, and will make you more likely to give up quicker if sales are low.
