Perhaps one of the best locations to find inexpensive, quality modeling supplies is your local craft store. These businesses carry a wide variety of products at extremely low prices. Seasonal sales and in-store coupons can often save you 50% or more! I bought my Patriot airbrush at 40% off at Michaels Craft Store.
Here in the states there are a few different options for big-box craft stores and many independent local retailers as well. These stores are treasure troves of inexpensive, high quality modeling and terrain supplies. The following are just a few of the various supplies I spied during my last trip to the craft store.
