At Amazon, Prime members can get two Anco Contour Windshield Wipers for $18 with free shipping. (Discount is seen during checkout. Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping adds around $6.) That's the lowest total price we could find for two such wipers by $10. These wipers feature a 1-piece design to help resist corrosion and freezing.
