A company called Head Entertainment, which is owned by the former managing director of Zavvi, has bought out several old Zavvi stores.
This offer is instore only; signs say 20 per cent off all computer hardware. Sorry no photos, but the price was being advertised on instore posters at 1900 today.
I saw this at the Bluewater store today. Head have also bought the following Zavvi stores - Cardiff, Bristol Broadmead, Bluewater, Dundee, Manchester Arndale, Leeds and Liverpool One.
Link is to wikipedia article about Head retail - I can't find their website.
