It's been some time this deal (half price) was on.
I was not sure whether to post it, as it is just a foldable chair with no speakers.
After reading some forum articles, I realised that there are people just want a comfy chair for their games....
Have some stock in my nearby Argos, and available for home delivery as well.
If you fancy a cheap sound-able gaming chair, you can subscribe to Official Nintendo Magazine. They give you an inflatable gaming chair with speakers. (Yes sounds weird but looks ok...) http://www.officialnintendomagazine.co.uk/
