I've been looking at some OSX applications, and I noticed they all seem to have a similar (and slick) inbox purchase experience. Is there a third party thats providing this? If one wanted to implement it in ones own OS X application, where would one go?
Examples include delicious library, things, the hit list, and coda.
Aquatic Prime is the only OS X shareware license library I know of. Could you provide examples of apps that use this "slick purchase experience"?
You can look at Golden % Braeburn. It's the one Wil Shipley wrote for Delicious Library.
A popular online store is Potion Store. I've never used it, having no software that I distribute for money.
