Just got this in the email. Not sure if targeted or not but seems to work like the other ones.

And as an extra gift from American Express, when you register your Card and spend $500 or more from Friday 29 November to Thursday 5 December, you’ll receive $50 statement credit.*

Maybe AMEX already know that. Apple probably AUTH your cc though?
Hopefully it will all work out.
