Hey RamSeva, not Roderick but I can tell you a bit:

Some rule prevents tobacco from being sent through the postal service in the US. You have to use a courier service like FedEx or UPS.

this is different than Canada, where you can send stuff through the postal service. So I can’t speak to how US orders work. I’m certain they would send each individual order to the US rather than having a warehouse there. Good luck!
