The British Purchasing Commission was a group that helped the United Kingdom buy things it needed during World War II. Just like you sometimes need to buy things for school or at the store, the United Kingdom also had things it needed to buy during the war. The British Purchasing Commission was in charge of finding the best places to buy those things and making sure the United Kingdom was getting a fair deal. They bought things like weapons, vehicles, and other important supplies that were needed during the war. This helped the United Kingdom fight the war and protect its people.
