Anyone have a good resource for polver. dirt, gravel, bulk mulch (or 3ft bags) and other landscape contractor supplies. There's several in the yellow pages but I want to see feedback from contractors perspectives please. Phillips in Raytown charges thirty a yard for black pol soil, twenty five for a ton of 3/4 gravel, and thirty to forty for a yard of mulch, seems pretty high compared to bits I've heard. Need to get relationships with the suppliers around town. Thanks for looking!
