Yeah, I was surprised to see them be that cheap. They seemed much cheaper than if you get them new too. I bet the out of print ones will be much more, though.
That's most likely true, but one would definitely need some perseverance and patience and a new chunk of money sometimes. If we were rich, collecting would be so much easier, hahaha.
Not a problem, glad I could help in some way. I can also help you get them; like Flintoff Cypress said, you'll need a proxy. I happen to use one for Y!JA, it's called
FromJapan. They're real easy to use and pretty cheap when it comes to fees. You bid on their site (rather than have someone do it for you) and they send notifications just like eBay, but you do have to put down a deposit. But, that deposit is only temporary and will be refunded unless you used it to pay for the items. For instance, you'll add a deposit for just 2000 yen and you can get both of the magazines with that deposit. You pay for the domestic shipping (not that much) + the items and after that, just the international shipping (comes with options so you can choose the cheapest). Your deposit can be withdrawal then. That's pretty much it. xD
If you got any more questions, though, I'll be happy to try and help.
