Very poor customer service experience. Ordered brakes for two of my vehicles on the 25th of the month. One all in one package with (4) rotors and pads all the way around and separately (2) rotors, front pads, and rear pads for the other vehicle. There was a RockAuto Only Rebate on the all in one package good until the end of the month (6 more days). These five parts shipped from three different warehouses. I get an email, which I did miss, the next day (now the 26th) saying There was a problem, some of my order was out of stock . I did not see this email until part of my order arrived from two ship locations and the rest didn t arrive. I now see that part of the order was cancelled and I only have the front pads of the brand I ordered. Of course it was now the 1st of the month, the rebate has expired, and I asked what could be done and was told they strongly recommend I update my phone number in their system so the next time I don t miss the email . I said OK, no rebate, I will just send back the front pads and go somewhere to order a matching set of pads. I then am told I have to pay return shipping for the front pads and that it really doesn t matter if I use a different manufacturer on different wheels. They also say if I don t want to do that, everything is now in stock, just reorder it . So they ran out of stock just long enough for a RockAuto Only Rebate to expire and the day after it expires, they have it in stock no problem? Very disappointed in how they handled this. Beware if your order ships from multiple different locations because if one location has a problem, you are left to deal with it. Also be wary of RockAuto Only Rebates . Finally, the fact that they process your order does not mean they actually have what you ordered. Their inventory system apparently cannot be trusted to be accurate.
BTW, I ordered the matching rear pads off Amazon with free shipping. Ordered the 4 brake kit off AmericanMuscle with free shipping - Saved 5% off RockAuto pricing. If there is a problem, you can bet Amazon will bend over backwards to make it right!
