Zip supplier

[swirlyarts]

Does anyone know of a cheapish zip wholesaler - or even a shop that sells zips? I had a look in Woolworths yesterday and they were £1.25 each!! I then went to the charity shop and grabbed some skirts off the 50p rail and have cut the zips out of those and I'm going to use the material for another project! Feel a bit guilty though cutting up perfectly good clothes so if anyone can help, that would be great.
