I weekly deep litter on wood pellets (if you're planning on doing a full muck out at the weekends it's not really a purist deep litter, more of a working week litter!) Take out droppings daily and bring down banks through the week then fully muck out at the weekend leaving the bedding up to let the floor dry out although it normally isnt actually wet...
Dont know about delivery but I pick up 250kg approx every 5-6 weeks for £50-55 (they sometimes have a sale on, random!)
It doesnt always 'look' the most glamarous bedding and does go a funny grey colour during the week but it's still dry and quite frankly the horses dont care what colour their bed is!
