Note; if experience has taught me from similar sites like Steam, Vocaloid' store likely takes a commission fee. So its more profitable for some Vocaloids to not be sold there.

Plus, in Japan in particular, CFM owns the distribution rights to Zero-G and PowerFX vocals, so their absence is explainable.
