Barney's price is actually full retail. The small grained goatskin Antigona retails for $2280 in the U.S. You are certainly searching for a very HTF style. I would say keep stalking retailers on a very regular basis (meaning daily) as when a small black grained Ant shows up, it will sell instantly. Perhaps try Lane Crawford. They have had a couple in the last several months and are based in HK I believe. I would say try the British retailers, like Selfridges, Harrods, Harvey Nichols. They have small Ants on their sites and may stock on a few black ones down the road. Check if they ship to your country too. All the retailers I mentioned will sell an Ant for less than U.S. retailers, like Barneys or Bergdorf Goodman.
Be persistent. You will find one.
Good luck!
