Whilst I was in Asda Chandlers Ford earlier today - picking up several large boxes of Fairy non bio (40 washes for £5) and a damn fine Ham Hock sandwich - I noticed they had Splatoon for fifteen quid. It wasn't on that end display where they've got a few Nintendo Selects it was on a separate display that faces the xbox games. I couldn't see any other gaming deals. I didn't try to purchase it, because I already own a copy. I don't know if it's national, but if you live locally and want a copy of Splatoon it's certainly worth a visit.
