You can change your Templett subscription plan at any time. Plans are prorated so you'll never lose out on any time you've already paid for, on any plan.
How to Change Your Plan
Visit the subscriptions page using the link below:
Select the new subscription that you'd like to change to, then click the "Subscribe" button towards the bottom of the page. Your new plan will go into effect immediately.
If you are upgrading your plan, any charges will be billed immediately. If you are downgrading your account, you'll end up with a credit that will be applied to your next subscription payment. You'll see the credit on your subscriptions statements.
