How do I pay annual subscription instead of monthly?

Hello - wondering if it's possible to pay for my subscription on an annual basis rather than monthly?

I see that your account melissa2ca is already subscribed to Premium yearly plan. However, it was due to renew by 16th May 2015 in which the payment was failed due to authorization error. You may need to check with your bank on this error and please ensure that there are sufficient funds in the account to avoid failure on the next charge attempt in 2 days. Please be noted that continuous failure attempts may cancel the subscription and downgrade your account to Free.

Hope this information helps! Thank you.
