If a Recurring Product has a "Product Option" with a "Price Adjustment", the price adjustment is only charged the first time around! Why?!
I think there should be a checkbox for the Product Option's Price Adjustment that describes whether or not it is a one-time offer or if it the product option will reoccur along with the regular product itself. Additionally, if the Product Option is a one-time offer, it should not appear on the Invoice/Statement or Order detail at the time of the next recurring cycle.
