American Express has a number of offers currently for cash back on several online steaming services.
The deals I've got from them are :
30% back up to $15 on Sirius XM Radio Inc. (including both internet-based and satellite-based), Pandora, Spotify, Sling TV, CBS All Access and Showtime. (expires 3/6/19)
Spend $5 or more get $5 back on Hulu up to 4x (expires 3/28/19)
Spend $35 and get $15 back on fubutv up to 3x (expires 7/1/19)
Amex deals are YMMV so check your offers to see if you've go them or not.
Also Ebates currently offers $5 cash back on Hulu (new users)
Standard Ebates blurb: To get cash back from Ebates you need to be signed up with Ebates. Then simply go to Ebates to get the referral to the store before you do your shopping. I also get a referral bonus if you use my links to sign up with Ebates.
