The offer is great. Can I stock up on it for several years?
During the sale, you can purchase up to 3 years of subscription. Please be advised that this doesn't work for downgrading. If you need to downgrade, only 1 plan can be taken, and it will go live only once your current subscription expires.
Note that only non-professional users* can set a downgrade. Professional users* can only extend their subscription.
