They also only give you the charged amount back also. So if you buy on contract you are SOL.
You might say "Well then I'll take the phone back to Apple and get an out of warranty replacement and use Amex refund to cover most of it".
But that won't work because Amex wants the phone after they pay you for it. They send you a pre paid shipping package.
Its great coverage but just not that great for a smartphone bought on contract IMO. The 90 purchase protection is nice though, my Amex covers lost items too with the purchase protection (Blue, Cash cards don't).
They very seldom ask for the phone back
