Classic Industries and AMD

A friend is doing major surgery on the back of a 1969 GTX. He has been buying metal parts that come from AMD (drop shipped directly to him) by purchasing them from Classic Industries, He had already bought a left rear frame rail and also needed a right side frame rail, but Classic said they were out of stock. My friend called AMD and they had one shipped to him the same day. The curious thing is that, while the prices for the parts were comparable between Classic and AMD (300 some dollars), the rail from Classic cost him $400 for shipping and the one from AMD cost $200 to ship. Buyer beware - make sure you compare shipped prices if you are shopping around...
