This reminds me of the last time I needed Windshield Washer Fluid. At a department store, they were charging $13 for a gallon of it, stating that it was All-Season. I balked at that price, so instead I headed to the Dollar Store and bought two half gallons at $1 each. I saved $11 and was happy. I mean, it freezes to the windshield at times, but most of the time it gets the job done.
