Materials run a wide range of costs depending on the class. For most classes with materials, we will either list the cost of materials (which may or not be included in your class), or list the materials in the class description, which usually indicates you will have to purchase them before the class. Many schools do sell the materials at their locations, so you likely won't need to go too far out of your way for them.
If you have a question about materials cost, feel free to contact us or the school directly!
