Data point: Bonus points from amex AT&T offer
Just a quick note to confirm that I've been able to get the 5,000 point "AT&T Wireless For Business" Amex Offer bonus by making a $151 payment to my AT&T personal account. I've done the $151 charge twice now and got the 5,000 bonus both times. I think the offer expires at the end of November , but AT&T lets you overpay your cellular bill and the negative balance carries forward, so you should still be able to take advantage of it if you haven't already.
