I was hoping this would be on my Serve card as well, but no dice there. I can't complain too much, though... two out of three isn't bad!

It disappears off the other card if you grab it on one.. You have to have two windows open to get around this, then you can get it on both.
I did this and it worked like a charm.
Anecdotally it usually works out (they give the credit for each), but in the event they have closed the loophole it's OK... I would spend the money at Amazon anyway. I just received an email for each card notifying me the offer was active, so all signs are that it will work as expected.
I just checked my Amex accounts online, and they have posted a $15 credit to each of my accounts, so using the multiple tabs does work as reported. It took two days after the purchases posted to get the credits.
I know the loophole could be closed anytime, but as long as you would be making the purchases anyway, there's certainly no harm in trying.
