My SA in Texas has the bag for you. I just talked to her on some other matter and I thought that I would check for you. It is pre-fall w/ goat in Jumbo size, just as you asked for. It is at Neiman, not Saks though.
Her email is Lauren_Gremillion@neimanmarcus.com. she is very nice and the Chanel specialist there. Tell her Rebecca sent you. Good luck.
