GREAT

Fast and easy. Shipping could have been less expensive but overall a good deal.

quick and simple

Great!!!

I'M PRESUMING THAT THIS IS A BRAND NEW BATTERY AND NOT A REBUILT. SHOULD IT BE A REBUILD, PLEASE CANCEL MY ORDER. THANX, FRANK

Thanks

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.

the Amazon payments feature was very slick.

Excellent

Best price on a holley carburetor online. I unusually use summit but even the shipping price is less, no handling fees either. I am hearing great things about the shipping so I am hopeful the 69 javelin is back on the road this week! If it works out I will tell all my motor head friends about this site!

So far so good

So far autoplicity has been a great shopping experience.
