Great products, and pricing

Awesome pricing. Needed Pertonix setup for my wifes 62 Mercury Monterey Convertible S-55.

Great service and packaged really nicely!

They carried the parts i was looking for at an amazingly discounted price. I'm not dissapointed even though the initial ship took 5 days to begin. Per their note they do inform the customer of 1 day to process the order and another 3 "business days" to SHIP. Seems like in this age of instantaneous communications the lag should be dramatically less. Generally, a more robust processing center can ship same day if in the same time zone and order arrives before 2pm - a goal to shoot for! ;)
