Walmart offers the Rain-X Expert Fit Conventional Windshield Wiper Blade for $7.97. Opt for in-store pickup to avoid the $5.99 shipping charge. That's a buck off and the lowest price we could find. While other retailers' prices differ based on size, these are available here at the same rate in most sizes from 13" to 24". (26" and 28" are available for a buck more.)
