Seen these in a couple of branches of PC World so looks like a national offer rather than store specific. The one I bought had no charger (any 2 amp USB charger will work) but did include USB cable, manual & packaging.
Tablet itself is pristine but that may just be the luck of the draw depending how it was demo'd...
Being a Nexus device this is almost certainly the cheapest way to get Lollipop (Android 5) at the moment.
PC World are also doing the Logic Nexus 7 2013 starter kit (case, stylus, screen protector) for £1.99 (that deal already posted elsewhere).
