product just as described, received in 3 days

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.

Amazingly cheap prices for what i was looking for, best online and pretty fast shipping. Took awhile for my order to be confirmed though, not sure why. But still impressed with the price set.

Easy payment process

Great prices will shop here again.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!
