A Gaijin's Guide to Doujin Shopping
For Touhou Project fans outside of Japan, it can be difficult to buy fan your favorite fan works. Most works are sold only in Japan, and most major doujin sales sites don't ship internationally. However, there are lots of resources available for international fans to purchase doujin works. I will try to collect them here.
Stores With International Shipping
While most sites don't ship internationally, a few do. These avoid the fees and extra shipping costs associated with forwarding services.

Digital Download Stores
Some sites sell doujin works as digital files. This avoids international shipping issues entirely.
Melonbooks DL is a Japanese-language download site.
Forwarding and shopping services allow you to order items from Japanese sites and have them sent overseas. A forwarding service gives you a Japanese address where you can receive packages. Once your package arrives at the forwarding service, they can ship it to you. If you are unable to purchase the item yourself, you can do so through a shopping service. A shopping service buys the items you want and forwards them to you.
Tenso offers both forwarding and shopping services.
i-TM4U offers a shopping service.
