I found grasslands in a search as the cheapest provider for stone chippings. They were not too far away and at £10 for a single delivery charge I thought that to be very reasonable. I found the purchase process to be straightforward and smooth as expected. The delivery turned up when expected though I wasnt there to receive it the driver left the 2No 1tonne bags in a considerate place with other building materials. The bags appeared to be well filled with material and contamination from other stone was virtually non existent. My only regret was ordering 2 tonnes not 3 as I needed more. I would definately use again.
