I believe they work in the Rifftrax app.
I dont see anywhere on the Rifftrax app to enter a code though?
It could be thats because im already a “friend” on that app and all the content is already available? Thats what Im thinking perhaps?
Oh, yes, that’s an issue a lot of people had. If you’re already a “friend” you have to cancel to get the benefit. Heh. Or hand the coupon to someone else and gain converts…
I think you need to enter them on the Rifftrax website.
the Rifftrax bonus content does not work through the Roku app. That one you have to go through the website.
In order to redeem the Rifftrax rewards, there are instructions here: Rifftrax free month didn't work - #17 by RiffTraxErik
These instructions are highly recommended because it’s easy to try and redeem the codes in the wrong place.
