As of late, I look at multiple sources. Often, once I find the part number of what I want, I will search it on Amazon. Since I have Prime, the shipping costs don't add up as much. There have been multiple times when I actually saved quite a bit by ordering from Amazon as opposed to Rock.
And I had the opposite experience. Last purchase from Rock was a pad and rotor "kit" for my truck. I bought Raybestos stuff. I took the part numbers from Rock and searched all over.......nobody could touch Rock's "kit" price even with their shipping.......Amazon wasn't even close even with free shipping.
