Premiere discount from AT&T data plan

Is there a discount on iPad data plans for premiere customers. I get 20% off for my at&t iPhone and the same on an iPad data plan would push towards it.

I have preordered a 64 gb wifi and a 32 gb at&t model. I am not sure which to keep. I am coming from a 32 gb iPad 2 which I managed the space on, but it only had a gb available when I sold it. I am only considering the 3g because I will be moving to london soon and traveling to africa frequently so the unlocked iPad will probably come in handy. I do also have an unlocked 3gs to use. Any opinions on the matter would be appreciated.
