Help with a Japanese online shop?

Question:

I'd like to buy the limited edition of 「死神と少女」 game for PSP

Apparently the limited editions are sold only the first few days after the game's release.... or at least I think so. I don't really want to buy the most regular one from Amazon.jp

Maybe someone could help me to search for it around the web? (japanese web of course). It doesn't matter if it's new or used. I'm not a gamer, but my friend has it and I played it with her, kinda fell in love with its story...

I don't really know how to search. It's my first time wanting/buying a game, so I'd really appreciate any help.
Here are some links for more info: http://www.takuyo.co.jp/products/shinigami/tokuten.html

Shipment within Japan is okay with me.

Answer:

Those limited editions are sold at certain stores. So you just call them to ask if they are available or go to the store.

You can click each link on your 1st link to go to each store.

This is one. for example
