Went into Asda in Halifax this evening and saw Supercar Challenge on the shelf for £25 for the PS3. This is a brand new release and is retailing around £30 or more everywhere else including Asda online. The game is excellent and is a follow up to Ferrari Challenge released last year. It is much improved on its predecessor in every way and I think it's superb value at this price.
Pretty sure this deal is national, as someone else mentioned the price on a racing forum.
Hope this helps somebody
