It was quick and straight to the point without a whole lot of dialogue.

So far so good...

Quick and easy!!! The shipping was FAST, the packing was great and the merchandise top notch! The shipping and order notifications were also much appreciated. Great place to get Auto goodies. I will definitely be back to Autoplicity!

Ordering was very easy and product was delivered within a week. I ordered a battery and it was received in good condition and works. I would recommend autoplicity to others.

I didn't get a shipping notice until three days after I got the product. It was exactly what I ordered and did arrive during the proper time frame

I didn't even know Autoplicity existed until I did some comparison shopping online! BEST prices, and IMMEDIATE shipping! I'll be back, for sure!

So far so good

THANKS

Autoplicity has made my parts search so much easier. With the best price gurantee, i can now make autoplicity my one-stop shop for all my parts needs.

Well, I'll start with saying this...I wanted a specific product from COBB tuning that they sell. It was priced lower than any other company so I bought it. This happened on the 22nd, I ended up calling them almost a week later to request tracking info. They were very friendly when they notified me it wouldn't be able to ship out till the 3rd of feb. For a 2 lb item I thought this was pretty slow. They apologized for COBB holding the order up. Its now the 7th, should get my item today!! Overall its a good company with friendly employees, Shipping time is lacking but a trade off for the lowest price. I would refer a friend for price and also mention shipping time expectations. I do believe there's something to be said for quality customer service and low prices...It's becoming harder and harder to find companies that posses such qualities. Honestly, if they had a faster shipping method I would give them a perfect rating.<br>
