Shipped fast and accuratly within a week.

Best price and easy to use web site.

purchased two shocks for my truck, best price online , they were here within a week. I will definitely order from them again....thanks....

Easy payment method

Best price I've seen online and the shipping is extremely fast. I would definitely use this site again for future automobile needs.

Excellent communication, quick, easy, and lowest price.

quick delivery of the parts I need to fix my jeep

Best price for Rancho Shocks anywhere on the net! Ordered by phone and CSR gave me a better deal on shipping then the automated on site calculator.

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.

Glad I found Autoplicity.com. Big potential...<br><br>Ordered parts on Friday, missed 1st delivery attempt to office yesterday (Weds), but received today (Thurs). Little slow on the shipping, but not in a rush for these parts. We typically receive UPS pkgs in 1-2 bus days from Chicago suburbs to Metro Detroit. This took a bit longer, but again - it was not a problem & well worth the savings.<br> <br>Wish web-site would actually separate items for just my car vs all vehicle matches. Finding what I wanted was very difficult, but I'm very pleased with pricing & follow through. I've been back on Autoplicity 2 times now looking for add'tl parts for another vehicle, but have yet to locate them amongst the 100's - even 1000's of results that do not match. If finding them were easier & these add'tl items offer similar savings, I would have spent hundreds more by now. <br><br>If this is a new company, hopefully they can correct the advanced search option as well. Entering a part by vendor name should net results when the brand is listed on the home page & can be found in general queries. Even when I entered the part # for an item it shows no results, but again - searching several dozen pages, I am able to find the same part #. The savings were worth the headache it took to find the brake pads for my BMW, so I won't give up just yet. <br><br>Thanks Autoplicity! Here's to a potentially great future!!

Quick shipping. Good info on sttud will definitely irder again
