It's perfectly convenient to buy supplies at the MATC book-store but I prefer to get my supplies directly from A&C Supply. The staff is friendly and between the group of them someone will be able to steer you in the right direction if you need assistance or help with a decision, plus if they don't have what you are looking for they'll order it. It's all pretty standard retail pricing and though you can probably find them cheaper online you'd end up losing out on S&H. Even though I admit to taking advantage of the occasional sale from Michaels I take pride in shopping locally at A&C.
