Paypal Yearly Subscription
Check out my latest WordPress plugin.
I had to make a plugin for a very simple yearly subscription, since all the plugins out there are overcomplicated.
This plugin uses PayPal ExpressCheckout method for payment and has a simple setting page to change everything you need.
It uses shortcodes to handle the pay button, the return url and one for enclosing content that requires subscription.
You can find this plugin here:
