easy shopping A+++

Thanx it was so easy to order

love how it connected to Amazon. Super easy !

Ordered on a tuesday shipped out today. Have fast replies on emails. Will most likely be buying from them again in the future! Job well done Autoplicity!

Quick and simple

So far so good!

1st order. Shipped super fast and prices are amazing. I will be back for sure.

Ordered a couple of items. The first was a air intake kit. I had put in all my info for my truck and chose one from the list to order. Won't fit. Called to tell them and they asked if I had called manufacturer...ummm no. Said I needed to contact them to verify wrong part. They were closed, so went to website. The part they sent me was a universal fit- for cars, not trucks, but did find right model- $90 more. Called back autoplicity and was told I need to go through email to get an RA# to return wrong part- site says I can call. Been on hold for over 20 mins and still waiting. Hope the Nerf bars I ordered fit! Update- they called me back, got my RA#. Very pleased with how Nick handled things- it was what I expected the first time. He verified the NERF bars will fit and will be changing the website so the universal intake does not show on list for vehicles with larger air outlets. Changing my rating to show my satisfaction with how it was eventually handled.

EASY TO ORDER

best price I could find...just ordered the product. Hope everything else is as good.

Autoplicity had fast shipping at a low price compared to other competitors. The price for the item itself was the lowest around so I think I got a good deal or my car. Would buy from again!

Great prices and user friendly website

Easy shopping experience

excellent company with great prices and even better customer service. my order arrived, and too my surprise i found that it was not the product i had ordered. the customer service was prompt and i was informed that unknown to autoplicity, the product i ordered was discontinued by the manufacturer and what i recieved was their replacement. this was all unknown to autoplicity and they apoligized sincerely and have rectified the issue very much to my satifaction. the product itself arrived in perfect condition and meets or exceeds my expectations. i will look forward to shopping with autoplicity again due to their great prices and excellent customer service.
