Usually, the hazarous material shipping charge is applied to each order, not each chemical. So you can save by putting several hazarous chemicals in a single order. It's still expensive. Most major metropolitan areas have at least one laboratory chemical supply house. You can often deal with them. They may not carry purely photograhic chemicals (e.g. glycin, CD-4) but the common laboratory chemicals (e.g.acetic acid, ammonium hydroxide, sodium hydroxide, sodium carbonate, etc.) and those commonly used in laboratories and schools (e.g. thymol, hydrogen peroxide, many fine chemical reagents) will be available at reasonable prices.
