NW Wisconsin | Cornerstone is 3 lb 15.5/3 is 5.16 per lb
Cornerstone 5 is 4 lb 17/4 is 4.25 per lb
Cornerstone K is 4.5 lb 20.5/4.5 is 4.55 per lb
Powermax 3 is 4.8. 22/4.8 is 4.58 per lb
So your best buy is cornerstone 5.
However Powermax 3 has a better surfactant package and at .25$ difference I would go with that unless you are running another surfactant for other products. | |
