Renewal for $39.99 Education/Nonprofit plan
If your current Education or Non-Profit subscription is not auto-recurring or if you have canceled your recurring billing, it is not possible to immediately reinstate your subscription.
You will need to wait until your current subscription expires before you can re-purchase your plan. To resubscribe again, you can click Upgrade to Pro on your Plans & Billings Page, or upgrade from the Pricing Page. Once you have resubscribed, your subscription will be on auto-recurring until you decided to cancel the recurring billing again.
