I have ordered from Rockauto.com twice and was pleasantly surprised by the service and quality of each shipment. Prices are hard to beat and the website is easily searchable for any specific part you're looking for. I recently placed an order for a Eastern cat for MY 01 on a Sunday and had it by Monday. The office is located in WI but it shipped out of a warehouse in PA. The price was lower than anywhere else I looked and it came with O2 plugs (because it has an extra hole in the front) and both gaskets. Heck, I even received and extra 5% off by Googling for a coupon and they were running a special for a free "Car Care for Car Guys" book. Oh I also received a pretty sweet fridge magnet!
