Bags or bulk?

At 11.1 cubic yards, buying bulk from a landscape yard is usually far cheaper than 150 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

1,200 sq ft × 3 in ÷ 12 = 300 cu ft 300 ÷ 27 = 11.11 cu yd 300 ÷ 2 cu ft = 150 bags (rounded up)
