Nintendo DS Lite : Joytech Armorlite Plastic/ Polycarbonate/Clear Case : £2 @ Sainsbury

I've been haphazardly looking for a polycarbonate case for my sons DS while out in the sales and saw this in-store @ Watchmoor Park. It was priced up as £4.97 but went through at £2. Most other highstreet places seem to be £5-£10 and I couldnt find it this cheap online.
