stinking water neck driving me crazy

...give me a few gallons of anti freeze to make up for what i spilled trying to get this one to seal, and she gave me 2 30 dollar 1 gallon jugs for free
Do I read that right, they are charging $30 for a gallon of antifreeze? Even the uncut good stuff like Prestone should be well under $20/gal. Autozone brand uncut is advertised for $14.99 here.
