X-Payments Subscriptions & Product Options
They subscriptions work, product price hijacked to be a setup fee.
Setup fees are NON Recurring. Subscription Fees are recurring. The current design has mixed the two and made a hash of it as a result.
At the moment, the subscription module is only usable when one does not have product options. That is because in its current state, product options only accrue to non recurring setup fee and not to the product. Product Options should impact the product price, not the setup fee of course
Moved this idea to X-Payments project at X-Cart ideas site.
