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.
Great price and fast shipping.  Good experience!
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,
The shipping was fast and the customer service was great.  I accidentally hit submit twice, and they promptly cancelled my accidental order.  If you have any problems, just call!
