Hello! I am a total newbie to the luxury world. I know there are Chanel bags that are really hard to get without purchase history. In the Bay Area, how hard is it to find a Chanel 19 in store (any) in colors beige, dark beige, or brown/ caramel etc? I am asking because I am seeing some on preloved sites for the same price as retail. Am I better off buying a used one? I do not have a large income and can't buy chanel bags all the time.
