The new subscription fees are as follows: 1  Monthly Plex Pass subscriptions will increase from $3.99 (about £2.40) to $4.99 per month (£3). 2  Annual Plex Pass subscriptions will increase from $29.99 (£18.30) to $39.99 (£24.45) per year. 3  Lifetime Plex Passes will increase from $74.99 (£46) to $149.99 (£91.50). Most of the price hikes are pretty nominal, but the cost of a lifetime Plex Pass had doubled. In other words, if you've been thinking about getting a Plex subscription, you've got roughly a week to sign up if you want to enjoy the original pricing.
