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.
