Hi guys. Call me stupid, but recently, I went to Don Quixote to purchase some foot care and skin care and payed at the tax free cashier. They packed and sealed it in their tax free bag. It's only when I get back to my room that I realised I'm not supposed to open it until I leave the country. I had no idea how tax free work because this was my first tax free transaction. But my foot was already swelling and I can't go out again without applying the foot care item. So I opened the sealed bag anyway, and used the item. So now my tax free benefit is voided. I read that before departing, I need to pay the consumption tax or risk fine. My questions are:
- How much is the comsumption tax I need
