How am I charged when I add PrepSwift?

The answer is that we won't charge you immediately - we'll instead charge you on your next billing cycle pro-rata. Suppose your billing cycle occurs at the first of every month, and you choose to add PrepSwift on the 15th of the previous month. In that case, you'll be charged about $11, which covers the ($8 + $2) GregMAT + PrepSwift subscription fees every month, and an additional $1 for the PrepSwift half-month before that billing cycle.

If you cancel the subscription before the end of the first billing cycle following your adding of PrepSwift, you will still be charged the fee for the period between adding PrepSwift and the billing period (up to $2)
