Spell books store the spells that an Arcane spellcaster knows. And, for the most part, an Arcane mage may never need to ‘purchase’ new spells for their book. Most Arcane mages, or others who like having such a tool, will add their new spells to their spellbooks themselves. Such additions cost nothing.
The reason there exists prices for spells in a spell book by level is twofold. Firstly, for any partly filled spell book, one can calculate its cost by totaling the individual cost that each spell adds to the item. Secondly, if there is ever an instance where an Arcane mage is unable to add the spell to the book themself, they may hire someone else to add the spell. If added this way, it is considered to be ‘automatically’ learned and the spellcaster need only pay for the service and the trait points. They do not need to spend the ten minutes of study or make an Arcana check.
