Goddammit I wish I hadn't waited to buy 7th Dragon 2020 Samurai. I had no clue how rare she was until I saw her going for $300+ on Amazon last week. Not to mention Nippon-Yassan has her for $350 (ahahahahahaha). Hell $200 is seems to be the low end with the going rate being anywhere between $300 and $400. Might have to bite if I can find her new-ish for ~$200 even if that's a batshit insane price. Maybe MF will find it in their kind and gentle hearts to issue a re-release.
I wish you luck.
The only Max Factory figures that I can remember getting released, at least in the last several years, are Saber/Kiritsugu [and even then, they're "revised" and not a typical re-release] and Zero Suit Samus/Samus Figma [that might have to do more with Nintendo wanting a re-release than MF themselves].
Other than that, they typically only do one run, which is probably why so many of their figures retain their high value. Either way, I hope you're successful in tracking down a Samurai for a decent price. She's well worth it.
Nah you can cancel whenever you want even when they just asked you for payment on a preorder as long as you do it before their designated date of payment.
Actually, N-Y has a new "no-cancellation" policy. They're a lot like AmiAmi, HS, and other Japanese stores now.
While they might make an exception occasionally [similar to AmiAmi], I wouldn't cancel too much if I were you. You'd risk the possibility of having all of your pre-orders with them cancelled and your account banned.
