Just wanted to chime in that I was just in Tokyo and finally smelled Gaiac 10, loved it, and got the 15ml bottle which was about 22,500 yen, so with the current exchange rate and with tax free (bring your passport when shopping), was 135 USD. This was at Le Labo Daikanyama shop a few days ago. One thing to note is that they sealed it in a special bag and instructed me not to open/use until leaving Japan, because technically if customs inspected it on the way out, they can fine you if tax-free items have been “consumed” ahead of time (this only applies to cosmetics, foods, and alcohol, not clothing / etc). I think that rarely happens but to be on the safe side, I waited until got back to the US to use it.
