Not sure if this is common knowlege or not but anything in currys with a yeallow price tag means that they have no stock left and you'll have to buy the ex-display one.
It means if it has a yellow price tag you can probably negotiate a better deal.
I just picked up a 16gb sandisk view for £50 for my Dads xmas & birthday prezzie :)
It's ex-display but thats better than refurbished in my book & comes with a 12 month warrenty still.
Anyway - if everyone already knows this feel free to ignore me!
