This post is all about Napa and their outrageous proce difference. So my Dad's friends chevy silverado 1500 needed a new mass air flow sensor or something like that so he went to the Napa store. They would order it and sell it to him with no extra shipping cost for $50.00. He then decided to go to the autozone, they had the same damm part, same manufacturer for the same truck for $30.00!!! Why is Napa so damm expensive????
