Macy's Pricing

On a commercial this evening, Macy's advertised Friday doorbusters. In the mouse print, they stated that when doorbuster supplies run out, pricing reverts back to normal, with regional differences.

Multchannel pundits --- here's a question for you. Is regional pricing acceptable? Should a customer in Milwaukee pay less than a customer in San Francisco? And how would you recommend Macy's execute their online pricing strategy? How should Macy's price the item online?
