you can buy it from Countrywide, I think they do pallet loads too. It's great stuff, I've used it before but not currently. Expensive to set up the bed but then far cheaper than chippings and quicker and easier to muck out too. It's not designed to be mucked out fully daily, just take the wet out when necessary and fill in the hole with fresh bedding. The bed works best if brought to the front of the stable (put a plank of wood across the doorway) so the horse doesn't mix wet with clean bedding when moving around in the stable. You can leave a little empty square in the corner for the water bucket to stand in. Aubiose packs down fairly solid, so the poo stays on top and is easy to skim off each day. If you find it's getting churned up and your horse isn't a box walker, it'll be because the bed isn't deep enough.
