Just got this in my email:
Get the Original Plex Pass
As a token of our appreciation, we’re going old school and throwing back to the original Plex Pass pricing for our original customers. This exclusive discount on a monthly, annual, or lifetime Plex Pass is available now through midnight (Pacific Time) on May 1, 2016.
This offer is only going out to a few of our long-time Plexians and isn't valid for those who didn't receive the offer, so please keep it between us.
All prices are in USD
