I called my bank and They said they didn’t have a thing called auto blocked, and it wasn’t them that blocked the transaction, it was amazon. @LucasDesu I tried changing the adress and it just won’t work. Maybe they’ve really cracked down on this thing and the vpn is just not going to work.
Alright, I was able to purchase it, what I did was add funds to my gift card balance, and then I purchased the book that way. I don’t know, maybe they were really paying attention to kindle purchases and knew I wasn’t in japan but it didn’t matter when I used gift card balance or whatever
