I want to set up a page with PayPal subscription gate away to my members area. It's a simple page with PayPal button which offer discounted subscription price for the chosen customers only.
Therefore I want to give one time access to it. So when the visitor leaves the page to go to PayPal to start subscription and then return to the page - access will be denied. The new access will be denied even if he/she do not subscribe. In short, it is one time visit. This will stop them spreading this offer all over the net.
Would appreciate if you provide the code or plugin for this. Thanks
