Buying gakuen heaven 2 from the official website

So I know GH2 has an eng patch, with another updated one in the works (and GH has one on the way), but I cannot for the life of me figure out how to buy the windows PC version to patch from their official website since it's all in Japanese and I cannot translate the page. The reason I'm not torrenting the .rar files this time is because I actually have the money to support the game and a fair way to buy and patch it :) I know a torrent would be much easier and I guess I could do that if it comes down to it, but I'd prefer to support spray since i adore their games.
Plus who knows, this may spur another company like jastblue to pick up and sub their other games if their's enough English support!
Any help appreciated, pictures are even more so.

Actually! You can buy it directly from Amazon.com! ^_^

It's a little pricey (It's over $100 CAD for me), but it's worth it to support developers!
