The promotion of Bitcoin via the increasing numbers of such sales sites will surely contribute to the growth in Bitcoin use right where it is needed - international sales,and low cost sales by small retailers.
Being a developer myself I was aware of this module. But also of the coinbase and bitpay plugins. I have to say that those modules are too much overprice. That the developers want to earn is a good thing. But 139 USD for a module where the premium paypal module is just 39,99 USD says it all. Most of the time the cheap modules give you a good head start for your Shop so beware of those expensive payment plugins.
