If you're not in Texas, you might be able to save on shipping costs by purchasing media at a local vendor.
For a great all-purpose abrasive, we recommend 40/70 mesh recycled glass. It will work for just about any application, and is usually cheap and readily available.
We sell the recycled glass for $10 per 50 lb bag on 40-bag pallets in the Online Store.

Northern Tool usually carries it and if they don't stock it, you can speak to a manager and let them know that you'll be purchasing consistently. Another option would be to do an internet search for "Recycled Glass in (insert city and state here)".
