Good morning! Thanks for your email and I am glad things are going well for you :)
In regards to the shipping method, I really don't think it is a good idea we ship everything together in one package.... If I may ask, where there any issues with the last shipment's shipping method, upon receiving everything?
I remember you said taxes were lower with they way we shipped the last shipment, that is because of the lower declared value and each package under the 16666yen threshold for importation duties / taxes.
