When you sign up for Premium or Pro, you choose whether to pay monthly or yearly. Paying yearly costs less: you get 2 months free. Premium costs $9.99 per month or $99.99 per year, Pro costs $279.99 per year. You can't pay more than one year in advance.
Is your subscription already running and do you want to switch to yearly payments? Let your subscription expire first and then sign up for a yearly subscription, or contact us. We'll then settle the subscription fee.
