They are NOT the crystal police. They also sell worldwide where they do NOT have the same regulations. Regulations are different here than in other countries for many reasons one of which is that the frequency bands are more tightly packed with users. They also sell to shops. As I said above, it is up to YOU to obey the rules. It's not illegal to buy a gun. It is illegal to shoot someone. Should they make it illegal to sell guns? Or leave it the personal responsibility of the gun/crystal buyer? A big jump in logic I know but it covers the same issue. Maybe you want to need a permit to buy a crystal?
