No, he probably missed that you said PayPal Standard or confused it with another post he just read when he replied. PayPal Standard is not supported by the pro-forms, only the buttons work with PayPal Standard. Sorry about the confusion.
If you’re selling non-recurring, do you mean a 1 payment subscription or a buy-now transaction? If you don’t give a trial term, then it’s better to use a buy-now than subscriptions for a single payment.

If you use buy-now, then to extend his access the user can be logged in to his existing account, pay again with the buy-now button and have the new paid time be added to the paid time he had left from the previous payment.
In your EOT Behavior panel there’s a setting to have these buy-now purchases extend the time he has left. See: [hilite path]Dashboard -› s2Member® -› PayPal® Options -› Automatic EOT Behavior -> Fixed-Term Extensions (Auto-Extend)[/hilite]
