Ordered parts for a brake job on my car. Did not get to doing job until the holiday week. A wheel cylinder was incorrectly boxed and did not fit my vehilce even though part number was correct. Rock Auto said too long for return, could file warranty claim, needed to purchase same part again first and then wait for a week for the part and then send in bad par for return.
Very poor customer servcice, would not recommend them.
