For now, I think the only place where you can purchase them will be at a LV boutique/Neimans/Saks location. Call now and get on their waitlist.
Although I'm guessing that after the initial rush, you can probably still call and get them to find and send one to you.
Of course that can change, you know LV, unpredictable.
IMO, I have a weird feeling that they might become a permanent item. I hope not.
heymom - Argh, oh well... did you hear if they will still be LE?
