Dell says that the Targus Manufacturer Part# PA357U (which is for the Lattitude C series) will work on my laptop. The challenge is, I need to buy one today due to the fact I'm heading out of town.

a) Does anyone know of a retailer in Chicago (north burbs) that carries this?
b) Does anyone know of a retailer in the AA terminal that carries this?

I cringe at #2, however I'm spending OPM.
