I just poured a 12' x 14' 3500 PSI concrete pad for a Sugar House I am building. I ordered 4 yards at $83/yard with a $75 delivery fee. No delivery fee over 5.5 yards. With all due respect, and I did it once, anyone who mixes their own concrete @ ~27 bags per yard is nuts. CRAIG CLARK , K1QX PO BOX 209 RINDGE NH 03461 603 899 6957
