Hi All! I am new to the purse forum. I have been learning a lot by reading threads and this is my first time to post. My friend left for London and Paris yesterday and I told him to swing by the stores in both cities. I would love to own a 30cm Birkin. What are the chances that one is available to a walk in client? Also which store would have the greatest chance? I dont think he will visit all the stores for me (afterall this is really just the biggest favor). Any thoughts on this?
