NAPA sells a decent, reasonably-priced pair of wiper blade refills for our 2006 XK8 for $5.99. If they last for a year (the typical lifespan for decent wiper blades in our neck of the woods), it will be tough to beat that value. Our car's wiper blade arms can handle either 20-inch or 21-inch refills, but the claw groove width must be a precise 6mm in order to fit properly....

NAPA's part number for these refills is 60-2001. My closest NAPA store doesn't stock them so I ordered a couple pair over the phone. They should arrive at the store by mid-morning tomorrow....
