This is a rushed post so I apologise, furthermore I was unable to take a picture:
1 LEFT on Guitar Hero and DJ Hero, I'd imagine that this is STORE SPECIFIC seeing as it had the red sticker with a pen marked price - perhaps clearing it from their store. With that said perhaps it's worth to call your local Asda and get on a quote on the price there.
Just come back from my local Asda (Colindale) and saw that they have the following in their entertainment section:
DJ Hero including turntable and wireless receiver PS3 (£35)
Guitar Hero 3 Legends of Rock incl guitar XBOX 360 (£15)
(These two are located on the counter at the entertainment section)
Skate 2 PS3 (£15)
Fallout 3 GOTY PS3 (£20)
Ninja Gaiden 2 Sigma (£20)
Dark Void PS3 + XBOX360 (£15)
I think you can get some of these games cheaper elsewhere (Ninja Gaiden Sigma 2 was/is £18 at play.com for example) but for those who want it straight away rather than waiting on delivery just letting you know.
Lastly I don't know whether or not some games are the same price on a different platform (i.e. Fallout 3 GOTY and Skate 2)
Happy deal hunting!
