Hi, I am working in the Shinjuku-shop of au in Tokyo, Japan.From the cheap ones to the expensive ones, there are various phones. So the price is different depending on the phone you want. There are lots of the campaign for introduction in Tokyo. Also you can get the voucher worth 3, 000 Yen. In this shop also has this event. You'd better go.
