They are currently in very short supply (rumours of a fire at battery factory in China) but are available at Currys on line today - don't know how long for.
I managed to order one from them last week just an hour before they went out of stock. Brilliant little machine. NOTE This is the 4G model with webcam - not the 2G.
May be possible to go thru Quidco and there was a code for £7.40 off but I think it has now expired? Still an excellent price AND free delivery . Only seen them elsewhere at inflated prices (due to the shortage).
