I just have to ask. I have been in the serious market for a chyc cabas and most of the authentication threads ask about auth cards or a tag on the inside of the dust bag. If fakes are getting that precise and hard to discern, what is to prevent scammers from taking a real card & dustbag and putting a fake in it? It worries me so much that I am starting to question buying anything on any site other than Neiman Marcus or Saks. Is there a way to ensure you don't get fooled?
