Amazon.com has a promotion going for $3 off each wiper blade.Rain-X Latitude wiper blades are priced from $8.95 to $14.14 depending on size.
During checkout, $3 discount is applied automatically for each blade.Super Saver Shipping applies for purchases of $25 or more.
Interestingly, the $25 is calculated before the $3 discount.My price for two 20\" blades was:
2 x $12.75 = $25.5 (qualifies for free shipping)
