This page introduces how to buy gunpla from Amazon Japan at a fixed price.
Simply access Amazon.jp, search for “ガンプラ”, and set the “配送対象” item on the left to select products that can be shipped overseas.
However, in Japan, there are many marketplaces that sell at a higher price than Bandai originally displays.
You can exclude the marketplace by adding “&emi=AN1VRQENFRJN5” to the end of the search result URL.
It’s a bit of a hassle, so I’ve prepared a link that excludes the marketplace so you don’t buy it at a high price.
Since it will be shipped from Amazon.jp, you can buy it at the price Bandai lists.
Please note that if you update or search again, “&emi=AN1VRQENFRJN5” will be added again.
If the Gunpla is sold out, it will not be displayed in the search results.
Please be careful not to make a mistake, as Amazon search results will show items other than gunpla.
