Don’t let Paypal or Amazon do the currency exchange for you. It’s not cheaper!
Two domains were purchased through a domain registrar, paid for by Paypal. But… There is a cost to letting Paypal do the currency exchange for you: NT$32.
If you let the bank do it, it’s just NT$10! So don’t let Amazon and Paypal do this, just pay in the original currency. It will be cheaper, and won’t pad the profits of these behemoths at YOUR expense.
