The subscriptions manager opens the cycle screen on the first of the month.
This cycle's box contents are set: a core selection every subscriber receives and two options subscribers choose between during a customisation window that closes on the eighth.
Reminder emails go out automatically.
A subscriber on the quarterly plan logs into her portal, swaps one option, skips the following cycle because she will be away and updates her address; the next charge date and the batch she belongs to adjust on their own.
