I will admit it has been some time since I replaced the wiper blades on my '99 Tahoe but this was a bit of a sticker shock to me! Stopped in at our local O'reallys and asked for set of 20'' blades for said '99 Tahoe. Was shown several options and decided on a pair of Bosch, total for the pair just a shade under $50 with a veteran's discount. If I had gone with Rain-X would have been more yet. Tahoe resides in the garage unless I'm driving it so these should last a bit I'm hoping!
Still recovering from the sticket shock,
It will pass with time I guess like all the other sticker shocks one receives now for the last several years.
