I skimmed many of the shops in Paris in April and saw no Birkins. But lots of Kellys, Bolides, Ados and other vintage styles I wasn't familiar with. I don't think there are shops there with several secondhand Birkins to choose from....but they may get one from time to time and you luck up and happen to be there when it is available. They may also have customers that they call first when they get one in and it never hits the floor.
