I'm from Singapore. I have done few trading with China before, because Singapore and China has agreement on open Bank Wire/Transfer so there is not admin fees charge to both side.
If I choose to wire/transfer the money from Bank so I don't have to pay extra USD45 right?
If the payment arrives correct to our bank account, it is okay to remove USD45 bank fee for you. Don't worry.
But if the payment that we received is less, then you pay use paypal to send the balance.
