Do you have to declare what is in your package for domestic shipping? I do not for Canada. I only declare because of import export laws and taxes that are required to be levied on international shipments. If it is not an illegal / prohibited item then you should be fine. Better check to see if it is legal to ship state to state. There are some crazy laws applying going from state to state. In Canada, I do not believe there is anything that is prohibited to be shipped domestically, other than things that are illegal. Cheers Peter.
