HomeGuide lists bagged crushed stone at $2 to $8 per bag. HomeGuide puts crushed stone at $10 to $50 per ton and $15 to $75 per cubic yard. Compare the two once you know how many bags you need; past a few dozen bags, bulk is usually the cheaper way to buy.

Weight to carry

Every cubic foot of crushed stone weighs about 111 lb. Check your vehicle's payload before you load a trip's worth of bags.
