Great service!  A+++++++++

I was very impressed by Autoplicity's customer service and excellent pricing on brand name products.  Also, they provided lightning fast shipping even as the holiday weekend approached.
As much as I want to see everyone in this world to "live long and prosper," I was especially pleased to deal with a company that did not export their customer service to another country.
I look forward to doing business again with Autoplicity.
