Re: AT&T will give you a credit for the price difference on the 920 due to their Black Friday sale
Don't let AT&T tell you they can't do the $50 credit on your account. I spoke to a rep who said they do not give credits for hardware price changes - he instead offered me a $20 credit. I politely said, "That is incorrect, I know plenty of people who were given the $50 discount today and I would like to remain an AT&T customer rather than go to another carrier." He put me on hold for a few minutes and came back with the $50 credit on my bill. Side note, when I initially ordered my Lumia 920 over the phone the rep wouldn't give me a free Wireless Charging Pad. The guy I spoke to on the phone today wouldn't give me the pad either saying it was an online promotion only, but I called back immediately when we hung up and another rep is sending it to me with 2 day shipping for free.
Bottomline: Don't hang up without getting what you want.
