i have a problem and seek advise of those who have mastered this before. by the end of the year, i'm moving back to florida from germany. the moving company has been selected, and we agreed to have them pack, ship and unpack. now, they are resisting to pack any darkroom chemicals, due to their insurance restrictions as they claim. i believe thenm, but the issue remains. i need to ship about $500 of raw chemicals to yhe us. what can you suggest?
