Bags or bulk?

At 4.6 cubic yards, buying bulk from a landscape yard is usually far cheaper than 63 bags. A full-size pickup bed typically holds 1.5–2 cubic yards of mulch, so delivery may be easier than hauling it yourself.

The math

500 sq ft × 3 in ÷ 12 = 125 cu ft 125 ÷ 27 = 4.63 cu yd 125 ÷ 2 cu ft = 63 bags (rounded up)
