The Royal Mail created a new pricing zone on 1 July, World Zone 3, which is just for the United States. Prices are now higher to the US than to the Rest of the World for some reason that I haven't figured out yet.
I regret, but I must follow suit. These costs are beyond my control. Since the shipping cost you pay to BAKKA is determined by the address entered at checkout, now packages to the US will cost more than to either Canada or Mexico.
Thank you, dear American customers, for your understanding.
