I did the same thing yesterday extepan. Only my excuse was that I had just finished the school semester and deserved an award.
Here is what I bought from one of the local Japanese stores........your not going to believe the price I got the first two for!
Endless Sorrow single - $1.00!
Unite single - $1.00!
H single - $3.00 (I already had this one, but this one had a different cover so I had to get it again. ^_^)
Appears single - $9.80
Ayu-mix II Non-Stop Mega Mix - $12.80
Ayu-mix III Accoustic Orchestra - $9.80
All of these were Japan versions too. I felt like I struck gold!
