Quantity

Sold individually.

A pleasure to do business with. Although the was about a 2" scratch at the edge of my windshield.

Your site has two prices listed for this part.

Best price by far! Fast shipping!

I like that your site has the quantity available for each item. I just tried to order this same item from another site which eventually canceled the order because the product was not in stock and they were unable to attain more from the manufacturer.

Everything went smoothly and my order arrived in a reasonable amount of time.
