Slate chippings in Kent?

Question:I'd like to have about a ton of slate chips to be delivered as landscaping small patch of garden. Anyone know of anywhere in Kent or a seller who would deliver to Kent? They are available from Woolworths on line for around £135 so using this as a guide price.

Answers:
Any good builders builders merchants will be able to supply these. IE Jewsons or Travis Perkins. £135 a ton seems very expensive they should be about £80/ ton delivered.
