Also keep in mind these dealers have insane overhead, owning a small shop I know the costs and I can only imgine what they pay. That goes to pay the parts guy to dig that part number up for you, to pay for the computer hes typing on, for the internet hes connected to, the phone you called on, the electricity to keep the lights on. Not to mention insurance, workmans comp, the list goes on. These online parts places most times wont even touch that part theyre shipping to you, they pay the drop shipper to grab it, box it, and ship it. They run a website parts directory, mark it up maybe 5-10% over their cost (think of the deals at their volume) and are happy being the front to the parts supplier, whos loving this online catalog selling tons of parts all of a sudden.
I dont agree at all with the inflated list prices, but again each dealer is allowed to set their pricing. A BMW dealer 3 miles from me is consistently 10% more than the BMW dealer 13 miles away, both in Bergen county NJ, yet the dealer in Manhattan is cheapest, even for a small shop like me that does a small volume of Genuine parts. However a smart consumer is an educated consumer, you do your HW and you get rewatded for your time. For most people its I need it order it.
