If you live in the US, make sure you know the facts about how Tamiya deals with "grey market" products (i.e., products bought from an overseas vendor, and shipped to the US)...
"Should You Buy Grey Market?
When thinking of purchasing Gray Market items, one consideration should be; how likely is it to need repair or warranty. Tamiya America, Inc. will only warranty items that are sold through proper distribution channels within the United States. If you own a gray market product it will need to be returned to the reseller or importer for service. You should refer to the reseller for more information." From Tamiya USA's

Likley it is a better choice to purchase from a domestic dealer.
