In my experience, Amazon isn't competitive when it comes to brake parts. Sometimes they're good for pads, but never with rotors (so far, my vehicles, my choice of parts). They do sell some brands like "Detroit Axle", for example, that have really good (low) prices but I don't use those.By the way, I was quite happy with the service and price from Rockauto. I searched Amazon, eBay, and local auto parts places. The rotors and pads were far less expensive even including shipping. For both orders I used the cheapest shipping method and still received the order in two days!
