Relatively easy process

Great price and super fast shipping.

good ,quick

great site

Shipping took about a week total from start to finish. A little slow as far as I'm concerned but the awesome price definatley made it worth it. Will order from them again 4.9/5

Had the lowest price around for a Thule 9025 bike rack. Shipping was also fast and inexpensive. I will be sure to use them again for future purchases. Order #9806 4/15/12

Absolutely perfect ordering experience! Ordered a part that is out of stock with most large retailers and at a price well below theirs. Ordered on a Friday, received Wednesday. I'll make Autoplicity my first stop in online shopping from here on out.

Very good first experience with Autoplicity. Order arrived promptly. No issues.

Good so far...

The magnaflow kit that I ordered was about $100 cheaper than any other site I could find. Shipping was fast, and relatively cheap too.
