Mandarake and Rakuten sellers have them for around MSRP and they even tell you which one you'll get. The only downside is you only get one face (looking left, front or right) in each box.
Megahouse seems to want to keep it around for a while. There's new releases and restocks down the line. So supply shouldn't be an issue.
Honestly they're not that good for the price, like others said the joint system isn't the best and they're incredibly tiny, gachapon sized even, so getting a full box of 6 is kinda overkill.
Still I love mine and I'm considering giving her hobby base joints. And custom faces, if I can find them
