There is more out there than Michaels.
In the world of art and craft supplies, you are almost always better off skipping the trip to the discount craft store. These stores lure you in with the promise of selection and convenience, but what you really get is a mile wide and an inch deep - a lot of types of crafts, but a small number of items in each section. On top of that, the quality is poor and the prices are jacked up through the roof. Plus you'll never produce work you are proud of if you start it off with inferior materials. Depending on what you are looking for, you can find infinitely better prices, selection, and quality if you look in specialty stores or online.

Try your local independant art supply store.
Even the markers are better quality at your local art supply store! These stores usually have friendly, knowledgeable service, and a much larger selection to choose from. Many have preferred shoppers discounts or specials, which are good to take advantage of.
