Good shopping experience and customer service, but I need to return one item. I started the "return process" on Ebay a few days ago but have not heard back from Autoplicity.com yet about how to return the item. Can someone please respond to my email with the answer to my question? Thank you. WM Lovelock

The two machined metal parts were rolling around in a big box. Banging against each others machined metal spines. the part should have packing that would not collapse. foam peanuts, not plastic air puffs that collapse during shipping. Was surprised box packing tap did not fail. That would have resulted in missing parts at point of delivery.

Looked around online everywhere for my spark plug set. Autoplicity had what I wanted at the lowest price. Thanks guys!

Great price cheapest around super fast shipping will go to for all other performance parts needs!!!!!

Order 11001 was placed on Thurday and was shipped out on Monday. The item was cheaper than anywhere else on the web. I look forward to getting my new side steps. Thanks Autoplicity.

Very fast shipping, always great prices.

Wanted to buy my parts on another audtion site but found the price much better on Autoplicity, and the service seems friendly.

Very pleased with product and shipping prices. Best price on the internet.Took a few to many days between order placement and shipping. Once the product was shipped the timing was very good.Talked with support-they were helpful and friendly.
