I use Stripe for my SaaS app, but for all my digital download products (ebooks and courses) I use Gumroad [1] which actually has really great fraud prevention. Not only that, but Gumroad will fight a chargeback on your behalf and if they lose they cover the fees. That includes both the credit card fees and the $20-30 chargeback fee. You know a company that has taken responsibility for the related charges will work hard to fight fraud. Disclosure: I really like selling through Gumroad (and once they sponsored a workshop I taught). [1] http://gumroad.com http://gumroad.com
