Wow I'm on a roll this week!
I have news! On a whim I decided to browse around Amazon and guess what I found? YES! Dr. Jart & Missha's BB cream can now be found on Amazon. And even better is that it qualifies for 2 day free shipping if you have Amazon Prime ^^! Of course they only have the two basic colors (Missha 23 and 21), but if one of these is for you then here's another source! You don't have to rip out your hair trying to find it anymore~ whoooo~. Right now they're selling for $17.50- the price fluctuates though.
EDIT: I also see a Skin 79 Diamond bb too!
