Sorry, redrex, I've been holding out for a better answer. I don't think this is going to be fixed on the classic exchange site. Here are some things others have done to work around it.
One suggestion I got was to select a non-commercial setting under License Type (such as “Donation” or “Try/Buy”) and include your external download URL in the item description, or support information, for interested parties to copy and paste. A file needs to be uploaded to complete the submission (for instance, a JPEG sample illustrating the effect/preset).
Some contributors have gone to the extent of producing a free “lite” version of their extension (e.g. a single script or action, or subset of patterns, from a larger set) as an example of what’s available in the full version. They also included a PDF outlining the benefits of the full version in the download package.
Can you make either of these work?
