FWIW and not sure it has been mentioned on here - I was in an Apple store the other day to just browse watches as I had no intention of upgrading to a S4...and they are all out of stock anyway eh? Wrong
Apple Store Southampton - showing on iStockNow as no SSG, SSSB or SSS, but they had all three in stock at 5pm. Basically I asked the guy how come as showing as out of stock and he said that for the Stainless models they have to have 5 in stock to show as available. Admittedly he only had about one of each in and no Milanese Gold left, but there was stock he said in the morning and they had been sold that day.
As it happens I bought a Nike+ 44 SG to replace my S3 SSSB (which they part-exchanged on the spot) as although I loved the gold, my other half pointed out that I upgrade every year (it was actually a year to the day that I had purchased the SSSB S3) and i lose too much money. The Nike+ was also not showing in stock so worth popping in to a store if you are nearby or passing
