Same here. We don't have to do anything additional to "claim" this reward do we? Like for the $10 credit you had to click on something on the 360. Are we good to go once we get the email? It is not entirely clear to me.
If so, I'm all set to pick up an iPad Mini for my son's birthday present. I have about $70 in RZ certs to make it $260, a 3x points RZ coupon to use (thus essentially getting back $15), and then the AMEX purchase to get back $50. Not too shabby... Plus I'm really close to qualifying for Silver RZ for next year. This and a few Black Friday game purchases should put me over.
Just says wait for the email and you should be all set. Just got mine. Got achievement Saturday.
