How do you buy a recipe in wizard 101?

You can't actually buy recipes in Wizard101. They are earned through gameplay and progression, not purchased. Here's how you can get recipes:

* Quests: Many quests reward you with new recipes as you progress through the game.

* Crafting: Certain crafting skills (like Baking, Brewing, or Jewellery) unlock recipes as you level up.

* Drops: Some enemies and bosses have a chance to drop recipe books.

* Shopping: The Bazaar, a player-to-player trading system, can be a source for recipes. However, they are usually expensive and you need to be careful of scams.

* Trades: You can trade recipes with other players. This often involves trading other valuable items or currency.

* Events: Special events often offer limited-time recipes that can be earned by completing tasks.

It's important to note that recipes are not sold by NPCs in Wizard101. You need to actively participate in the game and explore various gameplay mechanics to acquire new recipes.
