Impressive shipment time; great price for a very good product.

Absolutely the best price for the items order with fantastic processing and shipping time. My only complaint is that their customer service department failed to answer two emails I sent them regarding confirmation of proper fitment of the struts. To me, this is critical and needs to be corrected.

Everything arrived well packaged and in good order... It was shipped promptly, but hey, no accounting for the snow storm in the NW... I think UPS calls it an "act of God"... Thanks

Ordered Monday, delivered Thursday - just as promised. Best price among all reputable on-line parts dealers. Saved at least a third off the most popular dealers.

Great selection and fast shipping. Not to meantion the lowest prices anywhere on the net.

Great and user friendly.
