Yes, you can easily upgrade your membership from annual to lifetime. For each remaining unused full month in your annual membership, we will credit $5 toward a lifetime membership. For example, if you have six unused months left in your annual membership, you’ll receive $30 towards the lifetime membership and you will be charged $170 for the switch instead of the full $200 lifetime membership.
All you have to do is contact Plume support to request for a membership upgrade.
Only unused months on your annual membership are applicable towards an upgrade towards a lifetime membership.
