Bags or bulk?

At 7.4 cubic yards, buying bulk from a landscape yard is usually far cheaper than 100 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

800 sq ft × 3 in ÷ 12 = 200 cu ft 200 ÷ 27 = 7.41 cu yd 200 ÷ 2 cu ft = 100 bags (rounded up)
