As i manually activate members, i would like a system such as forexample, first month users pay 12USD thereafter they pay 11USD everymonth on a recurring basis using paypal. is that possible? It should be possible as paypal off the ability to charge any amount the first month and thereafter a fixed monthly payment the following months in a recurring billing. Please let me know if thats something u can do ? or possible integrating in the system... i don;t know how many will make use of a "activation cost function".
It ie easy to do - enable Paypal plugin , and configure in product settings: Trial 1 Price = 12 Trial 1 Period = 1m Price = 11 Period = 1m
