I’ve finally given in to temptation and bought some non-H Touhou doujins from Melonbooks and Toranoana. Naturally, that entails the use of proxy delivery services and after looking up reviews, I decided to try out Goody Japan. The entire process was really convenient, just create an account then fill in the form with links to the items you wish to purchase, wait for them to process the orders and that’s it. The service was fast and reliable and I got all my stuffs in just under 2 weeks.
I also bought a couple from Canvas. This one ships internationally and has an English site. However, the English site is not as well updated as the Japanese one. That’s not really an issue though, since you can just check the jp site for the item you want and then mail them the order in English.
