The “normal price” for this genuine Nokia charger is £9.95, but it’s currently available at the “special price” of £1.29. Er, partly because it’s sold loose and doesn’t come in a box.
The Nokia charger is of the 2mm variety, and works with a stupid number of Nokia handsets, including the N8. Hit the link for some listage.
Price includes delivery.
