I was in my local Asda today (Fratton store) and they had Tekken 6 on the PS3 for £20.00.
i had a quick look for XBOX 360 version, but couldnt find it. had about 5 PS3 copies left.
not sure if nation wide.
hope this helps somone.
I missed out on the Zavvi £17.95 deal so this is perfect for me!!http://uk.gamespot.com/ps3/action/tekken6/index.html
ASDA WEBSITE PRICE IS £34.71
i know online there are some slightly cheaper prices, but there is nowhere instock that i could find cheaper for the PS3!
