Got an email back today:
"Unfortunately, the sale has ended, please check back or follow us on https://www.instagram.com/haulathon/ for updates and special announcements. We suggest to try another payment method next time."
Wow, never thought of that.
NECA really is the worst company for getting figures into the hands of the non-US consumer (well, maybe Mattel with their WWE stuff is slightly better at being worse). 10 days of going back and forth for the issue to not even be addressed until after the sale, lol. They managed to avoid answering it long enough for it to no longer be an issue, case closed!
