The good news is that all gateways are going to be free. Or at least it is our plans. And all e-commerce fields 15 USD each, without tax. So say you want to sell files (or let others sell files) online on your site, you get Cobalt free and with only $15 you turn it in to e-shop for digital downloads.
More fields come later. As soon as we add another free 2Checkout gateway, and finish with SSI API, we develop some other e-commerce fields to sell different stuff from tangible products to any type of digital content.
