Picked one of these up instore at the East Boldon store near Sunderland/Newcastle. Cant find them on the Asda website, but theres a good chance they will be in stock in other stores too.
£3.98 for the full kit which includes: trimmer, blade guard, adjustable attachment comb, 3 close trim attachment combs, moustache comb, 2 AA batteries, storage stand, cleaning brush, clipper oil.
Nice little bit of kit for the price as a wuick trimmer, cordless and runs off 2 AA batteries.
Froogle has the next cheapest at around £8, same sort of price at Amazon.
