#1: Tires
#2: Wiper Blades:
We have two different styles of wiper blades we sell here. Here's the skinny on both:
This style of wiper blade has multiple pressure points because it has several arms that attach to the blade. This is the type of blade that's on most cars and works just fine for most people. These blades typically run about $10 a piece.
These blades provide consistent pressure across the length of the blade because of the increased flexibility in the design of the blade. These are higher-end and people tend to be very happy with them. These blades typically run about $20 a piece.
