East to order

Very easy to use and nice that you can pay with PayPal. Also the discount coupons and low price are great!

so far so good, easy ordering

Very satisfied...quick and easy!!!

The prices were so much better with Autoplicity I couldn't believe it was the same item. E-mail response came within an hours. Will buy from again.<br><br>Ok, the verdict's still out on this one. Autoplicity said my item was shipped two days ago (two days after ordered), but FEDEX indicates they've only received "shipment information", after four days. I'll follow up when I actually see the order.
