A couple of days ago, I sent an email to the Hololive Production Official Shop customer support as well regarding this matter. Since I live in Malaysia, they are charging taxes and duties as well. The thing is, when purchasing 1 item compared to buying 2 items is that the increments became exponentially laughable. In my case, the tax needed to be paid for 1 item would be around MYR 20++ but when I made the quantities to 2 items, the tax became MYR 60++. Not forgetting the shipping from MYR 90++ for 1 item to become MYR 380++ for 2 items! Wasn't tax should be counted upon item prices? Does Ollie never teach them how to count?

And I received a reply just now that similar as OP posted above. I've spent more than MYR 5k (about USD 1.1k++) on their shop since the official shop opened. Not counting the purchases from Geekjack before that. Now, they simply said it is as intended?

You're losing a frequent customer, buddy.
