Last month, HBO Max returned as a Prime Video Channel subscription. For the same $14.99/month price as subscribing through HBO directly, Prime members could once again bundle HBO Max with other streaming subscriptions with some small advantages. This week, HBO announced it will be increasing the regular subscription price to $15.99/month, effective immediately. However, if you managed to subscribe through the Prime Video Channel offering before the price increase was announced, you’ll be given a three-month grace period where you’ll continue to pay $14.99/month before the price increases to $15.99/month. Your first billing date after April 11th will be the first time you’re charged the increased price.
