The book shops in the alley sold the muggle course books that were needed for the electives and for the core classes. First, they had to buy the magical course books in Flourish and Blotts. Draco, Susan and Neville were buying first year books for charms, transfiguration, DADA, astronomy, magical theory, history of magic, herbology, magical religion, Latin, wizarding/muggle studies and potions. Next, they went to buy telescopes for astronomy, protective gloves and robes for herbology and potions, trunks and cauldrons for potions.
