CHARGE_FULL_PRICE

Replacement takes effect immediately, and the user is charged full price of new plan and is given a full billing cycle of subscription, plus remaining prorated time from the old plan.

Example: Samwise's Tier 1 subscription is immediately ended. His Tier 2 subscription begins today and he is charged $36. Since he paid for a full month but used only half of it, half of a month's subscription ($1) is applied to his new subscription. Since that new subscription costs $36/year, he would get 1/36th of a year added on to his subscription period (~10 days). Therefore, Samwise's next charge would be 1 year and 10 days from today for $36. After that, he is charged $36 each year following.
