I just uploaded v0.20 of the Brad Sucks Digital Download Store. Some small changes and one big one. It now supports Amazon's Flexible Payments Service:
Of course I can't actually offer it on my website as Amazon doesn't offer the service in Canada. So that's pretty weak. But for all you Americans: go nuts.
Update: I've pushed out v0.22 of the BSDDS, fixing a batch of bugs.
