Curry's and PC World are still selling these. Call store and ask them to check the SKU code 688394 and they can advise you of stores that have stock. I managed to snag the last ex-display unit from Kinnaird Park in Edinburgh.
Apparently some stock still showed at PC World Lakesdie (West Thurrock), Essex, Birmingham, Hull and Doncaster.
I accept this is going to be a limited deal but may still be useful for anyone local to call store direct and ask.
