Quick and easy.

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

The order didn't go through the first time so I had to add my credit card information twice, so I hope I only get 1 order and not duplicates. Thanks
