allow for promotional periods or varied billing amounts on recurring orders
My subscribers often have different monthly amounts or a promotional period before the base rate starts. For instance, customer number 1 may have 3 months at $59 before the regular rate of $99 kicks in. Customer #2 may be on a coupon that gives them $29 for month 1, $69 for month 2, and then the regular $99 starts. Doing this manually is a real headache.
