Funnily enough I got a subscription sale for $10.97 this morning, which is great. It'd be greater if I knew exactly what rights I'd licensed with that (so these custom deals are like SS's custom deals where we don't know the details).
It's less great if it's the equivalent of an extended license sale (which should net just over $25)...
I think the category it shows is subscription but that is more an administrative convenience than that the deal is like the subscriptions you can read about on the web site.
