It was great

Was very fast and reliable

Nice and easy to purchase an item we wanted and it was found cheapest here.

Always have the lowest prices for my Honda/Acura needs.

I received a 20 % off my next order email after my first purchase. I went to use it on my second purchase and could not find it. I called customer service, but they could not locate it either. Associate gave me $15.00 off a 211.00 purchase which was nice but not the $41.00 I would have received with 20% off. Still a good value. Thanks

Called with fitment questions. Very polite and knowledgeable. Thanks.
