Although Chatterbug’s subscription plans give you access to a set number of Live Lessons each month, you can always take more lessons when you’re out of credits. You can schedule an extra session just like any other lesson by picking a slot on your scheduler. The cost of your lesson will then be added to your next invoice, on top of the subscription fee.
If you unsubscribe after having taken a couple of extra sessions before your plan renews, you won’t be charged the fee for another month’s subscription, but only for the extra lessons on the last day of your subscription.
