Barrister & Mann are introducing a new soap/AS called Waves on 15 Nov. that is a clone. You will have to buy from Maggard in the U.S. who has cheap U.K. shipping I read. As well, it may be hard to get for a spell as they are a top artisan and their new stuff is in high demand.
AFAIK Italian Barber is the only store to ship alcohol internationally and it's entirely at your own risk , so if customs seize your package it's tough tiddy.
