To say it shortly: Highly recommended!
it has all the features you'll ever want to sell digital downloads and yet it's so simple it takes only a few minutes to figure out how to set it up and use it.
I'm planning to use it to sell digital download for musicians website and can't say how great it is !
In addition to this extremely powerful plugin you can buy addons to add various functionalities to the plugin or integrate it with other plugin/services (newsletter, payment gateways, audio player, Amazon S3 storage, and more)
Really appreciate that the developer follows a "create more value than you can capture" model.
Great plugin, great business model. Hats off to the developer !
Oh and one more thing: is there a way to add bitcoin integration or would you consider adding such a feature ?
