We order from Bobby's and Tico's. Bobby has 6 - 1 gal jugs of water for $12.54, that's $2.09 per gallon.

I normally go into Bobby's a couple of hours before they are going to deliver and discuss any substitutes. That way I can let them know if I will accept the substitute or just leave it off the order. There are no surprises when it shows up at the boat.
