Just go onto eBay, search for fo.Q TA-102 (or TA-32) and choose any site that offers free postage and a price of $35 or less. I have bought from many different suppliers and never been cheated. It can take up to a month to arrive. The limit is usually 1 packet per sale, but it doesn’t matter if the postage is free. I think the Japanese govt pays the postage to encourage export, but only up to a certain small weight.
