so far so good

I have a feeling these shocks are not available.

Good price and good deal on the shipping!

Great prices and fast shipping. Saved $100 buying here. Will do business again

So far so good

Really hard to find plugs - autoplicity had over 100 "in-stock" - great price also.

Placed an order with Adam on Monday, Nov 28th (#601). Very satisfied with Adam's technical knowledge and received my product on Nov 29th. The product is exactly as he represented and, because of this great customer service, I will place future orders.

Great price, I shopped around for hours on the web and no one could beat it, even with the shipping costed added in. The shipping was a little high, however, the price was so low it was still the best price around. Shipped in less the 48 hours. Thanks for a great deal and great experince.

great product lowest price

Of 6 other vendors I'd found, every one listed the exact same price for the product. Autoplicity was well over 10% less. Although it's like an instinct for me to shop around & compare prices, I would expect that Autoplicity will be the hands down winner on any & all future purchases. I don't know how they do it...but who am I to question them saving me lots of money!!

Great price and great service highly recommended. Will purchase again

Thank you! You were the cheapest and your service rocked! Got my item in less than a week.
