I wanna say leeteuk misunderstood the whole situation. If you look at the receipt it is written in chinese that this is superjunior "bar" who bought all these album and a "bar" is like the chinese version of korean daum cafe, and this is a group order of chinese elfs, not an indivudual. This is mostly all chinese elfs ordering their copies of album throught suoer junior bar, so the number shouldn't be suprising.
