Recall I had found a calfskin GST from Neiman Marcus and it didn't come with the authenticity card. (It was likely a return). The NM Chanel manager called Chanel directly to request another authenticity card for me. Chanel told her that under ABSOLUTELY NO circumstance are authenticity cards reissued even if the original was missing. I really love the GST and bought it pre-hike and it's Fall 06 & matches my ballet flats, so I don't know whether to just keep it. I guess I have my NM receipt and could always send it to NM if I ever needed repair, but selling it might be impossible - don't you think?
