The price of “Indigo naturalis” seems to have become much cheaper since I bought it.
At the “Seishin Shoyakudo Shop” where I bought it, the price used to be 5000 yen for 500g plus shipping, but now it is 4200 yen plus shipping. I looked for other stores, but it seems to be the lowest price. Secondly, “Mimaki Family Pharmacy” seems to be the cheapest at 4475 yen plus shipping.
I wonder if they got a few and got a little cheaper because I advertised it. lol
