First post so hope all is as it should be.. :S
I just got back from Comet in Kings Lynn having got a PS3 with littlebig planet in the box plus the choice of up to any 3 games at £20 each. I got 2 games (Call of Duty:World at War & Motorstorm:Pacific Drift) for a grand total of £339.99. The next best I could find in the shops was a HMV Rockstar games bundle at £224 including GTA4, Midnight Club & a choice from another 3 games. The culmination of them having no stock (Kings Lynn) & no real choice of games makes the Comet deal a favourable one for me for a 3 game bundle.
I got the impression this was nationwide in store only.
