Thank you foryou fast service, and knowledge. I will definitely be shopping again for my automotive supply needs.

I found parts for my car from google shopping and wanted to verify that everything was correct before order. I call the phone number and somebody picked right up and checked on everything for me. A++ seller. Thanks Autoplicity!

Best price I found on a web..was in stock and received on time within the week..

very prompt service,items were in stock and shipped next day,salesman was helpful and friendly.Will place in favorites and do buisness with again.

Excellent prices, but after a week and a half of hearing nothing I called to find out that my item, the customer service rep said it had been back ordered and I would receive an email once it shipped...my item arrived the next day and I received the shipping email four days later, no big deal just takes a while to get items, but you cannot beat the prices!

lots of details in description

Best price & fast shipping.can't go wrong.Will look to them again Thanks

LOWEST PRICE AND QUICK DELIVERY WILL MAKE ME A REPEAT CUSTOMER ,GOOD JOB FOLKS .

After seeing that Autoplicity was in good standing with the BBB and had favourable reviews reported elsewhere I placed an order on a Sunday evening. On Monday morning I already had a confirmation email and order number. On Tuesday I was notified that my order had shipped. Their price of $477 on the part I ordered was about $30 cheaper than Summit Racing, who I usually do business with, and the cost of shipping and handling was only a few dollars more. I haven't recieved the part yet but have no reason to think I won't be totally satisfied with the transaction.

Thanks for having a BETTER price than even the manufacturer on the chip I bought!
