I'm pretty sure these are discontinued. I didn't see any at the outlets during my last visit, so I'd say the only place to find one would be eBay.
Perhaps this might be close. I bought this couple months ago but they are sold out in the store and website also. I think you can get them at outlet store. I saw the same one but bigger size, more like a beach bag for $315, which is a very good price.
That is a super nice bag!!!
