I assume YMMV when it comes to the myriad of Japanese shops, but is Erolin itself legit? That is, it actually does give access to Japanese shops at the advertised prices that would otherwise be impossible for foreigners?
Inquiring minds want to know!
EDIT: If no one has any info, then I'll gladly take one for the team and give the a try when I get to town. Question though: are the pics on those Japanese shop sites legit? For example: http://www.x-ray9.com/companion.asp
