Bags are easy for small jobs. Bulk delivery is cheaper for anything above about 3 cubic yards, but needs a place to unload.
The price gap
A 2 cubic foot bag of mulch can cost several times more per cubic yard than bulk mulch. To compare, divide the bag price by its volume in cubic feet, then multiply by 27.
Convenience
Bags fit in a car, stay clean, and can be placed one at a time. Bulk needs a dump spot, a tarp, and wheelbarrow trips, and rain can make a pile messy.
When bulk wins
Projects that need more than 3 cubic yards, large lawns, driveways, and long paths. Many suppliers have delivery minimums or fees, so check the full cost.
When bags win
Small beds, container fills, patching, and areas that are hard to reach. Bags are also useful for materials that must stay dry, like concrete mix.
