Well, I'm not near a Yodobashi myself, but I do know that they deliver anywhere in the country (for free) I think. I could do it, but then maybe so could your girlfriend since she could get the stuff shipped to her address. That being said, I'd love to get my hands on another bottle of Rodinal! I'm not sure about shipping chemicals. They are pretty anal about a bunch of stuff here, although I've had chemicals from the US and Europe shipped to me in Japan no problem. Also, shipping costs would be based on how many packets and the weight, something that really could only be figured out once you knew how much you wanted of what.

Anyway, I'd like to help you out, but the next couple of weeks are going to be really busy for me, so I don't want to commit to something that I might not be able to do right away. Just FYI.
