Pretty darn easy

Order shipped quickly and Autoplicity had the best price. A pleasure to do business with. Thanks

Autoplicity had a MSD Timing Twister that was discontinued and no one had in stock. I called 6 places before getting in touch with them. Ordered part and had it in a matter of days.

I ordered Thule Aero Blade Load Bars as part of a bike rack for my Infiniti EX35. The part was order on Saturday, 04/14, and arrived at my doorstep on Tuesday, 04/17. And that was by FEDEX Ground shipping. Very very quick, and the right part to boot. Excellent service.
