Official Apple USB cable for Ipod shuffle (3rd gen)
I picked up an official USB cable from my local Tesco yesterday for £2. I'm not sure if it's nationwide or not.
The price on the shelf said £8 down from £14 (ish) but it scanned at £2. I wouldn't pay £14 for it and probably wouldn't pay £8 but though £2 was quite cheap for an official Apple cable (currently showing as £12 online).
