I ran across this listing on Amazon US. The cardboard is in Spanish but I'll be using the stuff from my Conversion Kits so that doesn't matter. The listing is from a vendor in the UK, and shipping for four to NY, USA came to under US$15 total (but will take nearly a month). They appear still to have some in stock.

Just figured it was a good score and I should share the info in case anyone were looking. Folks across the pond might be able to research the vendor and get better access to a local listing. Part of the fun of the game for me (in the absence of opportunity to play it live) is finding deals on older stuff and expanding my collection. 😎 🍺
EDIT: MY order just shipped and they're coming from Mannheim, Germany. Interesting.
