Well, you've looked around and hopefully you have liked what you see and you now want to get the mangas for yourself. There are several methods I can suggest for doing this.

You could try Ebay or one of the other on-line buying centres but you can't be guarenteed of getting what you want there, and you can't even be sure if they are going to be on sale. Which leads to my suggested way of getting the Manga for yourself.

My suggested way would be to look up the name of a Japanese book shop in your area. If you don't have one then look up a book store that sells international works as well. For me that's a LOTE store (Languages Other Than English), for you it could be something else.

Once you have found one, you might want to ring them first to find out if they can order this stuff. It saves wasting your time on a visit... But that's your choice.

Then go armed with the ISBN numbers of the books you want. The ISBN numbers are like a books barcode. (Most of you probably already know this.) Each ISBN should be unique for that book so if you order through the ISBN your order should not be mucked up! I say 'should not' because this is the real world, and God only knows how it works! Since you know the titles of the manga as well, it's probably a good idea to supply them as well, since when your order comes in, it makes it easier for the store to notify you. If they ring and say ISBN Blah blah has come in, it's not going to mean anything until you get there!

The following is a list of ISBN numbers and titles. Good luck and happy shopping.
