Please pay the invoice within 48 hours otherwise please msg me first, I am okay with hold or payment plan for valid reason. I don't take responsibility after package shipped out and no return to all sell. I don't take responsibility if the package involved into any tax issue. However, please feel free to contact me if you feel I can help with anything. I don't take responsibility doesn't mean I don't want to help. I have no pets and I don't smoke :) (Most of the time I can only ship items on Sat as the USPS open hour ( 9a-5p) is fully conflicted with my workday schedule. )
