I hope this hels someone. It started with my Explorer AC compressor locking up while I was doing 70mph. I found out that Advance Auto Parts matched other store prices. NAPA was $208 Auto Zone $270 and Advance was $171
I was luck I printed all of them because when I went to Advance Auto they wanted $309. When I showed them a print out from their own web site for the same part for less the manager freeked then matched it. So I suggest that you serf before you shop. I saved over $300 with all the items I bought that day.
