Price shown is for a 19" AquaBlade, their top model - a 17" 'Silver' blade is $3.00.
One day sale (till midnight, 3/14), online only - but you can order today, specify in-store pickup, and they'll hold them for a week or so.
The following description is for the AquaBlade, which I've been very happy with after several month's usage:
"Keep your windshield clean in the stormiest of weather with this Valvoline wiper blade. Providing ultimate all-season performance in an aerodynamic design, the AquaBlade is constructed with 100% natural rubber and a graphite coating for smooth, chatter-free operation. Each blade is reinforced with a stainless steel spine for stability and consistent streak-free finish over the entire wiping surface."
