Can I switch my subscription plan?
Of course! You can always change your subscription plan in your account settings.
You always have the ability to upgrade to a more extended plan in order to take advantage of a lower price. If you do this, you will be prorated - based on the time left on your current subscription billing cycle.
If you want to downgrade to a plan with more frequent payments, you will receive prorated account credit that can be applied to upcoming renewals or future subscription upgrades.
