Prime Video Channels has a new deal where you can subscribe to Discovery+ for $0.99/month for 2 months. This is for the ad-supported plan, which normally costs $4.99/month. The ad-free plan costs $6.99/month and is not on sale. Note that, unlike most Prime Video Channel subscriptions, subscribing to Discovery+ through Prime Video Channels does not currently give you access to the Discovery+ app. You’ll only be able to stream through the main Fire TV interface or through the Prime Video app on any device. One thing the Prime Video Channel subscription of Discovery+ does give you, however, is access to 11 live streaming channels which will be integrated into the Fire TV’s live program guide. This offer ends tomorrow, Sept. 15.
