It was alot faster than the AutoZone.
Very high level of responsive customer service, wow!  And the items arrived immediately, so fast I thought there might be a mistake.  :D

My first order and I must say, very impressive! Awesome prices and super-fast shipping direct from the manufacturer. Couldn't ask for more! I will return.
