This was a great seller, I chose them because they had the lowest price with incredibly low shipping for the item I purchased. It arrived on time and in great shape thanks to UPS. The product was the one that was described and it fit perfectly (exhaust). I will definitely be checking back for great deals and service. 10 out of 10!!!

It was one of the few places I could find online that sold the Warn gaskets I was looking for. It was a great price, shipping costs were ok, but overall I had a good experience and I'll definitely come back.

Excellent transaction, ordered on Monday received my goods on Wednesday...

Mazda cargo mat for the CX-9 SUV came within 1 week. Mat fits perfectly; just as described. Autoplicity had the best price listed for this product; we are very pleased.

Great Price! Fast Shipping!

I just finished a transaction with this company and decided to write my very first post, based upon my experience with them. To be honest, a few short hours ago I was wary of how this would turn out. There had been a miscommunication with shipping and it started to go down hill. Lo and behold, something happened that is rare today. The company, from top to bottom put all of their efforts together, communicated with me even during a Holiday and rectified the situation. Not only would I recommend Autoplicity to others but implore potential customers to use them confidently. Their work ethics and customer service is top notch and I am very grateful for my renewed trust that there is more than just big box, fast food companies out there. Thank you again!!

Autoplicity saved me over $300 on just one item!!! I can't wait to receive my Borla Atak Exhaust and install it on my new 5.0L F150. Thanks Autoplicity!!!

Great prices and item shipped quick!
