I was thinking of the Sakura hairs as 2 versions of the same hair, but I guess apart from the labeling they're really more like 2 different hairs. :') I suggested that purely because I liked every item in the set (which is so rare), not because I wanted to get more for my money, but I suppose that's still a form of greed. xP
The only other avatar site I've played is Subeta, where the cash shop trunks work like KofK's MTs so I've definitely never thought "wow I'm getting so many extra items!" when I buy an MT/TT.
I feel like someone who says that may only mean for reselling purposes.

I think people have adjusted to a new "standard": TTs that contain 4 items. At least I have - I get excited when I see a set with 5 items, and I deliberate longer before buying a set with 3 items.
Out of curiosity, how much are KofK's costs per month?
