Amazon offers two Valeo 900 Series Ultimate Wiper Blades
(most models) for $20
with free shipping
. (Add two to your cart, and the discount appears at final stage of checkout). That's tied with our February mention and at least $14 less than the lowest total price we could find for a pair of these wipers elsewhere. (Most stores charge $11 to $14 each.)
Note that before you proceed, you'll have to select your car's year and model.
