That's just stupid.
Sure, I can understand that she gets annoyed that people bids online in auctions to get her single instead of purchasing in person, but when a.) It's not feasible for some fans to do that, and b.) the number of copies sold are so few that it's impossible to manage, it becomes an issue of management idiocy. Clearly this single isn't meant to be sold publically. It's just a gimmick thing for her, involving Sasshii in it. So it's for the "first come first serve" fans who shows up at an event. Not for "fans who want to buy" like you do with a single sold in an official store online for example.
I still hope it can be sold like a normal single, but time is passing, and it seems strange that they're just pressing 850 copies now and not more.
