I ordered a 1000kg ( bulk bag) of plum slate. It took 5 working days to arrive and had to be manually moved off the truck by the delivery driver by hand and put where needed all with a palet jack ( poor driver) . The slate was very dusty when arrived so couldn't see true colour of what the plum slate was like until moved into position and washed. I was quite disappointed with the quality of the slate as there was lots and lots of green and white slate and grey pieces plagued with small crushed slate Which was rather annoying because if you was putting the slate down on membrane it would more than likely clog it all. The slate needs a really good wash before going down as it was covered in a film of clay by the looks of it and needed a good blast with the hose to get it off . In the the picture on the site the plum slate looks more plum and intense than it does in person. Happy that I paid the price that I did and would have been disappointed of I had of paid more.
