Though there are a great many art supply stores out there and many more that specialize in certain items, we thought we'd list a few of our favorites.
Jerry's Artarama is by far the overall best priced supplier we've found. They also carry hard to find items. Shop by supplier BRAND HERE.
As the name suggests, Cheap Joe's is also reasonably priced.
Dick Blick has been around since 1911 and has a huge selection. Certain items are a bit pricey.
