So, they had to buy weapons. Finding a weapons dealer in Great Britain was very hard to do so, especially for someone like them who knew nothing about the black market. They spent months looking for a seller until they eventually gave up. Harry decided instead to use some of their remaining money to buy a portkey to America. There, he bought two semi-automatic rifles. It was scary how easy it had been for Harry. He did not even need to present paperwork. Just tell his name and that was it.
