My order was for blue 40mm slate, and I chose Stone and Garden for their competitive price, availability, and delivery options. The slate was delivered "overnight" which I found a little confusing, but all became apparent when it arrived as promised, but by a local carrier. Obviously "overnight" meant it was trunked to a local depot. There was no problem in offloading by pallet truck, even though my road is on a slight incline, and was wheeled down my drive to where I wanted it. The slate was exactly as ordered, although it had not been pre-washed, but again that was easily resolved once it had been laid by hosing it down. I would definitely use this Company again, and have no hesitation in recommending them.
