Where to buy Ayu stuff in Tokyo?
 

Is there any shop in Tokyo that sells Ayu stuff? I don't mean cd's or dvd's but other stuff? It doesn't have to be official (coz' official stuff is only concert goods?). We (me + my family) are planning a trip to Tokyo in December and it would be nice to know if there is a shop to head for for Ayu stuff. (And I'd like those CDL tickets too!)
