I've worked easier sites, but overall fairly straitforward. Would buy from again.

Easy site to use.

Wish shipping was cheaper

Good so far

Was looking online for the best price on a part and found that autoplicity had the lowest price and free shipping on it. I ordered it and it was shipped the next day along with tracking number. I will be ordering a few more parts from autoplicity. Order Number: 27769

Great prices, hopefully good product?

Autoplicity got my air filters shipped next day after I placed my order. Cheap prices, and good customer is what they stand for. I will definitely be looking at their site in the future for my car needs. <br>

Order Process was quick and easy. I would highly recommend this site.

Easy to use

Great and Easy to Use Website

The price is right but shipping cost is high. I bought a transmission seal for $12.91 and shipping was $13.31. The box it shipped in was about 10 times bigger than the part itself. Reduce the box and reduce my shipping cost please ! Else than that the part was in good condition, it was packed right and shipping time was reasonable.
