Stores like The Home Depot , Lowe's , and Walmart are convenient for smaller projects as they sell gravel in manageable 50-pound bags.
These local businesses specialize in outdoor materials and often have "bunkers" filled with various gravel types, from pea gravel to river rock. They typically offer both pickup and local delivery.
Buying "directly from the source" is often the most cost-effective method for massive projects. While some are wholesale only, many are open to the public for truckload purchases.
