13. Windshield Washer Fluid
Hard to skip this deal, right? As little as $1 for a gallon of off-brand windshield washer fluid? It’s virtually impossible to find a better score, right? Let us tell you why that’s wrong.
These windshield washer fluids aren’t effective in cold weather. So, as soon as the weather turns sour you’re in trouble. So while you’re paying extra for name brand fluid, that’s because it’s guaranteed to work even when temperatures go as low as 28 degrees below zero.
Luckily, you can avoid getting tricked if you read the label carefully. If it says the product is not effective in winter weather, walk away.
