Drip Content

Ok Im sure this topic has came up before but here is my dilemma,
four options of a magazine subscription
digital monthly and yearly
hard copy monthly and yearly
which when they pay for inhere is an address field were it can be mailed out by using your add on for that
and the monthly diggy is simple
but the yearly digital is the trouble is there a plugin that can do this
Basicly the drip feeding of the yearly is my problem.
thanks
