Well I have found them ...Wilkinson's (AKA Wilko) stock them but don't show them on their web site my local store has them at a very low price of 50p per pack of 2 so I'm off to by their entire stock from that store so i don't run out of them Vileda sell them on their own web site at £1.19 ....hay i saving loads ......just call your local Wilkinson's see if they have them in stock (Stock Number is - 02291536)
