I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for.  Items were ship out in 2 business days from the original manufacturer.  Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

I was very pleased with my transaction with Autoplicity.  My order was shipped the next day and received the following day.  The pricing was also the best I could find.  I would definitely buy from them again and recommend them to others.
