I have set up a payment plan and (as a customer) selected following:
1. Selected the free $0.00 plan.
2. Selected the "Featured Category" for an additional $4.00 per month.
3. Non-recurring.
I submitted it to PayPal an all went well with PayPal ($4.00 received)....however..
When checking "Payment>>Orders, it shows Completed, however $0.00 paid.
Could it be that there must be at least some (ie:$0.01) cost for the plan itself?
