It was great

Great shopping experience

I liked the ability to pay with PayPal. It was quick and easy. It was unbelievable how quickly the order was received-And with free shipping! Great experience!

It was quick and easy and matched my part to make sure it would fit. Just waiting to see how quick shipping will be now.

Good to do business with.

called for invo very helpful

I ordered a Grant 1103 Steering Wheel, Order Number: 16767. Great prices, quick shipping, good customer service, an all around deal. Thank you.

I'll admit to being skeptical at first, but the price was worth the risk. Turned out to be one of the best online transactions I've experienced. Received item 3 days after purchaseing and the best price I found. And I looked hard! A+

Unbeatable price and super fast shipping! The website is easy to navigate and there is a wide range of products to choose from. No need to go to the auto parts store when you have Autoplicity.com

I was a bit concerned buying from a online retailer I had not done business with before, but Autoplicity is now on my list of preferred vendors. I was sure there would be some problem, as the part I ordered was $73 cheaper than anywhere else online (too good to be true). Well, the part arrived super fast, and was exactly as I ordered. I did not hear from them immediately after ordering, but received confirmation and tracking info when the item shipped, which was two days after ordering. All in all, a great, money saving experience.<br><br>Update:<br>While I am still pleased with the service I received, I find it odd that Autoplicity emailed me and offered me a refund of $5 for writing a review. It has been a couple of weeks since I posted my review, and I have yet to see any credits on my credit card.
