Just flew back from Paris. I have no flagged history previously but this time my global entry was flagged with a big "X" on it. The customs officer asked me to go to the duty area. Surprisingly, the officer called me by my first name and told me that he knew about my purchase in Paris. I believe the Pablo system has linked to the US customs system. I was glad that I was being honest and helpful in the duty process. I was charged 9% on the exotic bag and 5% on ready to wear. He warned me that if I was not honest, he would have charged me 4x from the duty paid. It took 30 mins for the duty process, paid with CC, and I walked away with a smile.
