PartsMarket Their shipping is very slow, they ship a different part than they advertised, and their return process is not only a nightmare, but imposes the shipping costs ,both ways on the buyer who is completely innocent. STAY AWAY. Internet

i ordered a part based on both a specific part number and providing my VIN for compatibilty.  They ignored both and shipped the wrong part.  I then ordered again, this time paying double to choose a part where it had already been removed from the car and included a photograph. Several business days pass without the part even being assigned a tracking number, much less shipped. 

Meanwhile, I run into a nightmare return process on the first part.  They impose a contorted return process that forces the buyer to use a dropbox-like service to store photos with a third party, then provide a link to those photos to PartsMarket.  Except the PartsMarket software won't accept the links, which they later acknowledge as a flaw in their own system (but make no effort to resolve).  After finally getting the refund request submitted, it has been ignored.  In the end I have just filed a complaint with my credit card company and had the charges reversed.  STAY AWAY from these shysters.
