Well yesterday all the new stock started to appear at around 11am but did appear to start in London stores and filter out to the rest of the UK throughout the day. But it really was a case of being lucky looking at the right store at the right time. I missed the black 7+ appearing at Southampton literally by 2 mins. But fortunately i saw one appear at Basingstoke and managed to bag it, another person on here got lucky too but equally another person just missed out. So no real pattern.
