B&Q are selling these for £2.40 each at the moment which is about half the price of anywhere else i can seem to find.
The stuff is really very good (Auto express test winner - http://www.autoexpress.co.uk/products/products/235642/interior.html)
and leaves a nice matt finish to your dashboard and kickplates.
Its also part of the 3 for 2 offer they have on car cleaning products at the moment so you can get 3 cans for only £4.80 or £1.60 a can which is a an absolute bargain!!!!
