Scotts 2 cu. ft. Nature Scapes Advance Mulch $2.52 (Reg $4.97) at Lowe's
31 bags of mulch: $3.33 * 31 = $103.23 - $25 = $78.23
That comes to $2.52 per bag - almost 50% off!
Don't need 31 bags? Buy them anyways - the way Lowe's returns works, you can buy 31 @ $2.52 each and return the ones you don't need for $2.52 each. That way, the ones you do keep are still reduced (by how much depends on how many you keep).
