How can I provide unlimited free downloads?
To limit potential losses in case of inadvertent misconfiguration, we have a daily limit on the number of Free Checkouts that our system will process for each seller.
However, you don't actually need any special "download service" like E-junkie if you aren't selling your download and don't need to restrict access to paying buyers only. Here's some ideas to provide free downloads that don't require E-junkie:
If you just want people to download a file for free and don't need to issue each person a unique link that expires, then you can just upload the file to your Web site, or to something like Google Drive, Microsoft OneDrive, Apple iCloud, or any other free file hosting service.
Then you can manually provide that file link to anyone you want, or if you want the download to be publicly-available you could make a link to it on your site, just like you'd make a link from one page to another:
<a href="http://www.yoursite.com/path/to/yourfile.ext">Click here to download my file</a>
If you at least want to collect names/emails, but you still don't need to issue each person a unique link that expires, you could have a generic HTML contact form on your site that submits to any generic form-handler script -- or even a subscription form for a mailing-list service like Aweber, MailChimp or GetResponse (all of which can also be integrated with your E-junkie sales) -- which then leads to your free-download page after the form is submitted.
