I have been working on something for months and all the WP solutions have been clunky and not quite right. I have tried Devs in Eastern Europe and in India, Bangladesh and England. And then came WPSmartpay, which did exactly what I wanted, was easy to set up and has great backup. I now have a subscription based site without the bloat of other plugins, and I'm sure WPSmartpay will continue to get better with each new release. The AppSumo deal is amazing..do it now.
