Just picked up a pre-owned wii console for £22.50 from the old Oxford Street branch of HMV. They told me they had several more in stock. Originally these were £45 but as they're closing in a few days all pre owned Wiis are half price. I'm pretty sure they said all pre owned consoles will be half price but I can't be 100% sure. Up until yesterday they were advertising they had no pre owned consoles in stock. I just happened to pop in today and they've listed several pre owned consoles back in stock (or found in a cupboard as the cashier told me). If you happen to be going by there tomorrow it may be worth having a look at any consoles they still have left. I remember they had the DS, DSi and possibly a 360 in stock.
