Hi! I'm researching the options for my wife's 3rd year anniversary gift, and was thinking about getting her a Birkin. While she has quite a collection of bags (mostly Fendi, Louis Vuitton), she doesn't have anything from Hermes, although she has often expressed her love for the orange Birkin. I want to surprise her, but I'm really afraid of buying the wrong bag. Also, I don't really know what to expect to pay... I've seen advertisements from $1000 all the way to $30,000, and I'd really rather not get ripped off. Also, is buying directly from the store the only way to ensure authenticity? I would really appreciate any advice I could get. Thanks!
