Filesprout is one of the easiest ways to sell any file from your Dropbox, Amazon S3, shared hosting, or any cloud server. You host your files (Filesprout never see them). To get started simply choose one, pick a price, and use Filesprout to create a "buy" button link which you can share on your website or across the Internet.
With Filesprout you can add buttons to your RapidWeaver site, Wordpress blog, Facebook fan page, Twitter profile, or Squarespace site. As soon as somebody downloads you work, you get paid.
Filesprout does everything. The payment is processed via PayPal or Stripe, and the purchaser can then download the file from your storage via Filesprout website, so the file's location is never exposed. And you get paid directly.
Filesprout charge 5% on each sale. So you get 95% of each transaction immediately - deposited directly to your PayPal or Stripe account. There is no sign-up for you or the buyer, and no monthly fee nor contract. Plus you control your files' whereabouts at all times.
