The average windshield wipers cost is about $30, depending on your make and model.
If you drive a common model, you can buy replacement wiper blades at your nearest auto supply shop for approximately $20 to $30. Rare and luxury models will cost a bit more.
Some places will help you install wiper blades for free, like AutoZone, if you buy them from their store. You can also get a mechanic to perform this service for a cumulative fee of around $50.
If you’re being quoted much higher than $40 or $50, there might be a problem.
