Gamestation are having a huge half price easter sale. Similar to that of previous Christmas sales.
This will likely be both online and instore.
A worth while quote maybe "New releases and Nintendo DSi is set to benefit from the promotional activity, with up to 50 per cent off recently released software"
Heres is a link to MCV's article http://www.mcvuk.com/news/33851/Gamestation-plots-high-impact-Easter-marketing-push
This should be rather good with alot of high end titles receiving good reductions.
