I sent my order for some comp cams lifters on Monday 1-16-2012 at around 8:30 and the Item was still shipped on the next day Tuesday.  This was awesome.  I received my product on 1-19-2012.  They have had the fastest turn around time that I have ever delt with.  I would highly recommend them for your auto parts needs.  They also had the cheapest price I could fine, including the shipping fee.
I like the fact that they sent me an e-mail that my item had shipped and gave the shipping number for tracking.
very simple easy to find the parts your looking for..
Very happy with my purchase and product from Autoplicity! Highly recommend.
Item arrived promptly (4 days after order), price was good and item was as described.
