This may not be the case when trying to buy some rear quarters, but I bought a inner fender from AMD, and I was looking around at all the different sites for one, and yes the inner fender was cheaper on all sites then buying from AMD, but it turned out that they all wanted a $100.00 or more for shipping, and AMD only charged me $17.00 for shipping which made the over all cost of the inner fender almost $60.00 to $70.00 cheaper going through the AMD website. Not sure if you have investigated that on AMD's website or not, just thought I would throw it out there in case! Good luck man!
