Bags or bulk?

At 23.1 cubic yards, buying bulk from a landscape yard is usually far cheaper than 313 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

2,500 sq ft × 3 in ÷ 12 = 625 cu ft 625 ÷ 27 = 23.15 cu yd 625 ÷ 2 cu ft = 313 bags (rounded up)
