Just picked up a PSP 3000 model and 2 games for the princely sum of £137.01. (Unfortunately, hmv on-line deals are never as good as the ones available in store, so don't expect to find it on-line).
Deal consists of PSP 3000 with any two games from the platinum range, i chose Pursuit force and Killzone liberation.
Plus they were also doing a 2 for £20 deal as well. i chose Final Fantasy crisis core and god of war chains of olympus.
Even though it was in-store only, just the console and two games for 137 must rate as a good deal, and with the other two as well for just £157.01, i was extrememly happy.
The store happened to be the oracle in Reading, so can't say wther or not it is national, but would imagine so.
