About shipping books:
Within the United States, the USPS offers a very favorable rate called 'Media Mail' that applies only to books and similar printed matter. If you order one or more books AND one or more models, everything will ship in one package at a rate higher than media mail. We can not predict which course will result in the lower rate. You can either make two separate orders, or you may test both options at check out.
Beyond the United States shipping books is expensive, but there is no benefit to splitting book and model orders.
