You would probably be able to do it with paypal buttons if you don't want to buy eCart. I could help in a premier support ticket if you wanted to do it quickly and it would be cheaper than buying eCart if this is the only site you plan on adding commerce to.

Hello Ray,
thanks for your reply.
I would like to add one payment for registration and then you have full access to all episodes.
I already looked at paypal button but once you pay you are redirected to a "success" page. But what then? I don't know how to get to the user record and update it.
If it's too complicated I will ask for a premier ticket. Just let me know what the customer decide.
Thanks again.
Tony
