Has anybody used Goodchip Equestrian Rubber Chippings, near Doncaster?I need to top up an existing sand and Rubber chip arena, and these guys seem good with graded/washed Rubber chips and national delivery. Just wondered if anyone has any experience of them or if there are other good suppliers. Prices seem to vary between different suppliers from £65 per tonne to £200 per tonne for the same washed, graded chipped tyres.
