What good timing! I was doing my manga rounds today and at the used bookstore, Book-Off, I saw the first/limited edition of Koi Koi 7. Since I have the other two LEs already, I allowed myself to buy double just to be a completist. Fortunately, being used, the price was cheaper than if I bought the regular edition new (only $4), so I didn't feel too badly about wasting money. I've updated the entry for the first volume and replaced the cover, but rather than having to flip there, here's a comparison of the two covers (LE on left, regular on right):

While I'm at it, here's the damage for today:

Kinokuniya:
Shonen Magazine (1 year subscription, not cheap)
Dragon Age (1 year subscription, not that cheap)
Dengeki Daioh (1 year subscription, not cheap)
(Alas, I decided to not renew my subscription to Young Magazine. They never featured Yuuko-rin anyway.)

Bookoff:
Koi Koi 7 LE
Ai Ren 2 ($1!)
DearS 1 ($1!)
Rayearth2 1,2

Asahiya:
Tsubasa 6 SE
Negima 6
xxxHolic 4
Sailormoon 11
Atashi n' Chi 1

Animegamers (special trip):
