Creating a book on Leanpub now costs $99 (leanpub.com)

"After the author royalties, PayPal fees and chargeback costs, our gross margin on the storefront is about 8%..."

I'm surprised they accept Paypal at all, given that Paypal offers no seller protection for anything but tangible goods via tracked shipping.

This is going to be psychologically difficult for users to stomach, I suspect. I'm surprised they didn't instead say they'd just take the first $99 of sales - that would put off far fewer people and unless the average book fails to sell more than a handful of copies, it shouldn't take much longer to collect the revenue.
