Was in Argos in Cardiff today (Queen's Street Arcade branch) and they had the new Ipod Nano's on at the above prices.
I was in a rush and didnt have time to speak to anyone there, but the sign said Managers Special, Clearance Price.
These are the latest generation nano's, I dont know if they had them all in stock, or if they were the display models they were selling, but they were brand new, came with all the boxes etc and those are great prices. I've checked the website and the prices are the usual prices for these models so is instore only, but i dont know if its only the cardiff branch. Its worth noting that the 1st generation ipod nano 4GB refurbished by Apple is available for £99 on the apple website so this is definately a good price.
