The listing seemed clear and informative. So far so good ;)

Free shipping on a seat, awesome. Charged for shipping on the seat cover? Doesn't make good sense to me. Either way, Kirkey is the best on the market, and you had a great price. Sold

I appreciate the Amazon link during payment.

Best price, quick and easy.

Your phone kept disconnecting me so I had to order through web, which had internal error as well.

I ordered a new clutch on June 12, and the item shipped the same day. Had the item on time as expected. They also beat all other retailers prices by a significant amount. Their shipping costs were also reasonable. The only issue I experienced is that it is virtually impossible to get order status from their Website if you do not have an account. Anytime I used the link provided in the order confirmation E-Mail would always return an error.

Excellent service,super fast shipping,before I could get a tracking number, my package already arrived.<br>Will most definitely do business again.

Quick and easy
