I have been hunting around for a a bit and can't seem to find a plugin that does what I need, so time to ask....
I would like a site visitor to be able to pay to have a few questions answered. The way I had envisioned it is that they pay with a PayPal buy now button , and when the sale is complete they go to a form page to submit the questions, which are then sent by email.
I know I can put the form page as the return url for the PayPal payment, but I want to make sure that the customer has just paid for that question. In other words, they get to ask the questions now because they made the payment. If they want to ask more later, they need to pay again.
I have looked at the membership plugins and the e-commerce as well, and none seems to have that functionality.
Any suggestions would be appreciated.
