Very pleased with my purchase and Autoplicity. Got the best price on the internet and received it very quickly. Product arrived just as discribed. I highly recommend Autoplicity for your on-line shopping needs.

I was pleasantly surprised to received my order the following day.With ground shipping I was hoping to get it in 4 days to 6 days but this is amazing.You guys are great, thank you.

Awsome service and prices,Thanks alot

Autoplicity was quick and easy. Painless web format. Shiped right away. And reasonably priced too.

Great to deal with both online and over the phone. Buy with confidence.

I ordered new leaf springs for my Jeep Cherokee. Its already headed out to me. Ordering was nice and easy. I'll post more once i get it.

I consider myself a very good online shopper. Especially for auto parts. When I ordered a set of Eibach Prokit Sport Springs, I thought I would give Autoplicity a try. Online reviews were very good for this retailer and I am very happy to report that my springs were delivered via FedEx within 5 days of ordering! I asked for an update via email after 2 days and received an immediate response. Happy as can be, and I'll be back.

Great prices and super fast shipping. Found my new online parts store!

I was a bit concerned buying from a online retailer I had not done business with before, but Autoplicity is now on my list of preferred vendors. I was sure there would be some problem, as the part I ordered was $73 cheaper than anywhere else online (too good to be true). Well, the part arrived super fast, and was exactly as I ordered. I did not hear from them immediately after ordering, but received confirmation and tracking info when the item shipped, which was two days after ordering. All in all, a great, money saving experience.<br><br>Update:<br>While I am still pleased with the service I received, I find it odd that Autoplicity emailed me and offered me a refund of $5 for writing a review. It has been a couple of weeks since I posted my review, and I have yet to see any credits on my credit card.

I found great prices and they shipped immediately. Best deal online.
