Thumpr

On Monday I placed an order for a Moroso Battery Switch (which was competitively priced BTW) and sitting here Wed afternoon I've got my switch in hand. Autoplicity was perfect every step of the way, including immediate notification of the order receipt, notification of shipment, even notification that it had been delivered (and it was waiting on my front porch). Packing was suitable too. Couldn't be happier. Buy with confidence. Kev

Quick turnaround and the best prices on the web!

Easy checkout, great price

I ordered a Derale 14204 Trans oil pan from Autoplicity -<br>it arrived quickly, in good shape (was well packed for shipment)<br>More than pleased.... (best price was a bonus)<br>-HBP-

Autoplicity had the lowest listing price for a part which I had done extensive research. To make the deal much sweeter, free shipping! On top of that, part was delivered in only a few days! Really, there was no reason NOT to order from them. Great prices and fast response are the reasons why I look forward to continued business with Autoplicity. Overall a positive experience, so I highly recommend.

I did a price comparison for hard-to-find Redline motor and tranmission oil of over 30 different vendors and websites through Amazon, E-bay, Google, etc. and Autoplicity had the best price by 25-30%. It was a no-brainer to order from them, and their website is easy search and manage. And their shipping charges aren't too bad either.
