Excellent transaction, I will continue to shop with them.

Fair price

item was as described. good value.

Fast and easy

I ordered street performance brake pads. Autoplicity had the best price on the net and were shipped quick. Can't wait to get them installed.

Very competitive pricing and non-ridiculous shipping prices. Sometime they don't have what I need in stock, or enough of what I need, but overall, very happy with their service.

Good so far.

the site is well laid out. some products have very little product discription

Very Quick and easy to place an order, let's see how fast it arrives!

My dealings with this site have been great. I made a mistake on my address and emailed them to change it. I got quick responses every time. Would definitely use the site again.

Entered promo code wt10 for 10% off and free shipping and it didn't process when I checked out

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 price!

Pretty simple so far

Fast and easy had what I needed. Also could not find what I was looking for any where but here. Thanks

The order didn't go through the first time so I had to add my credit card information twice, so I hope I only get 1 order and not duplicates. Thanks
