Woot discounts a selection of Bosch Evolution All-Season Beam Wiper Blades to $7.99. Shipping adds a flat $5. Although some retailers charge less for a single blade, buying two or more grants the biggest savings by taking advantage of the flat shipping rate. (For further comparison, most local automotive stores charge at least $13 for a single blade.) Choose from a range of lengths from 16" to 28". These blades feature a bracket-less design, dual steel spring tension, and symmetrical wind spoiler. Deal ends May 31.
