Just e-mail me if you want to buy anything listed here...
So emailing the guy is fine. Having the money is fine. Getting the money there is another story entirely. Getting a Money Order seems to be the most feasible thing at the moment, but that introduces a couple more questions, such as "How do I get one of those?" and "Where do I send it?" :\
I suppose the best I can do for now is send an email to him, so I might as well do that, then I'm heading to bed~
