Amazon offers one ACDelco Clear Vision Wiper Blade with prices starting from $13.73. (You can mix and match the sizes as needed for your vehicle.) Better yet, add two to your cart and the price drops to $20 during checkout. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, it adds around $7.) That's tied with our September mention, savings of at least $12, and the lowest total price we could find. It's available in 10 sizes and each blade features a wear indicator.
