I ordered 2 rear window struts for my '06 Jeep Wrangler. a week later, I received a steering linkage part for who knows what vehicle. I contacted customer service. The lady was nice enough, but I had to return the part (time and fuel from my pocket) and the new parts will be late. When it's their fault, then they should expedite shipping the new part. Where's the savings now?
