Report
Ordered two large bags of sand. They asked to call before delivery so that someone was at home and could show where to put. As a result, they left for 20 minutes, and upon their return the bags were in the middle of the yard. Closing the space for the second car and restricting the exit for the first. The store said that we are fools and they will not rearrange anything. I had to make a return of the goods and then they took it, and we ordered in another place.

Brilliant. Excellent prices on decent timber and great service/advice on hand. Tight for parking/loading in the yard but always seems to work out.
