I live in the U.S., and I if there was anywhere I could've preordered the rest of the Kyoryugers from, I would've done it. I was checking a couple of websites daily in the hopes of preordering them.
What I've found is that, as someone new to toku and to import toys, it takes a surprising amount of digging to find viable options. I've been able to preorder the rest of the Figuarts I want; Kyoryugers are the only exception, since it looks like Bandai decided to give up on State-side Sentai releases right after Kyoryu Red. More's the pity: much like Kamen Rider ShinkenRed, I would've happily bought all ten if they'd been released. And maybe Dr. Ulshade Violet and Cyan from the final episodes.
