Faster shipping than I expected. Easy order process. The ignition switch was my problem and Autoplicity part was exactly what I needed at a price better than anyone else had, with shipping included. I will definitely look to them again when I need any more parts for my Monte Carlo SS.
Only slight negative would be it took a few days to get an email with tracking number so I would know when my part would come. But once I got it, found it was coming sooner than I originally thought, which was great.
Very fast shipping, the product should arrive today acording to UPS, and I order it 2 days ago. The customer service is also great.

Thanks again,
Very fast shipping and bottom line prices for every part. Awesome website. Will be telling all my friends about and using again for sure!!
Entered promo code wt10 for 10% off and free shipping and it didn't process when I checked out
