This page (
https://www.tunecore.co.jp/artist?id=202690#r572567) shows the full list of available sites where this can be purchased. It also does the same for other BLIND SPOT albums, so I wonder if I should maybe leave this link in their artist page?
Either way, for simplicity's sake, I only put iTunes, amazon, mora and recochoku in the "available at" section on this page.
