Question: Ron, Harry, and Hermione use polyjuice potion a lot. I'm confused as to how this is. In The Chamber of Secrets it is revealed that it takes a month to make. It would seem unlikely that Hermione would carry around a cauldron and potion ingredients and waste a month making the potion after they had a plan. If Hermione had made them over the summer, she would have only had time to make a few before she would have to leave with Harry and Ron. How do they get all their polyjuice potion?

Chosen answer: It's explained a little more in the book. Hermione swiped Mad-Eye Moody's stock of the potion when Mrs. Weasley wasn't looking. And it's possible that, when they ran low, she simply replicated it with a Doubling Charm.
