This Amex offer is solid (though not as good as the prior targeted bundle offer) since it is a rebate on the full Disney+ cost (or solid subsidy on one of their bundle versions).
It's available on many of my/my dad's Amex cards, including:
Business cards:
Blue Business Plus,
Amex Business Platinum,
Bonvoy Business,
Delta Business Reserve Business Gold
Personal cards:
Amex Gold,
Bonvoy Brilliant
We didn't find it on:
Amex Platinum,
Delta Skymiles Blue,
Delta Platinum,
Delta Skymiles Reserve
