It's not really worth the hassle for me to do that myself, as you can buy them many places.
I have not checked out wholesale prices of these fuses, but it wouldn't be worth my while to sell them onesies and twosies.
Maybe on Amazon fullfillment perhaps, but that would have to be an at-cost service.

I'm trying to avoid eBay and Amazon as there is no way to know if you are getting a clone/copy.  I called SIBA USA, they gave me 3 US websites to try. Only one even listed the fuse, no stock, minimum order of 10, and it's a SPECIAL order. Not a good situation.

They're not located in the US, but TME carries both fuses needed for your BM237 and sells them as singles (they're in Poland).

* SIBA 7017240.0,5
* SIBA 5019906.11

That's very cheap.
The SIBA by far the best fuse I've found on that size. 1000V, 30kA, and nominal 650mV drop.
The Littlefuse equivalent 508 series is only 10kA and double the resistance (and 500mA only).
I'm pretty sure 500mA would be OK in this application, and 10kA is plenty. I have asked Brymen. Several factors to consider though if you want to get into the nitty gritty of it. But as long as you have a fast acting ceramic of 400mA odd in there and a high enough breaking voltage for your application, no problem.
I'd be curious  to know if anyone else and direct equivalent to the SIBA, it seems to be a special snowflake.

Local Oz rep for SIBA is AU$11.30ea, ouch.

If that were truly the case for these fuses, at any rate, I would not have expected people here to be having the amount of difficulty in buying them that they seem to be having.

You might yet be able to make some profit on it via Amazon fulfillment, but that would obviously depend on the wholesale prices.  Given the high retail prices you've seen, it might be worth checking out.

Is that wholesale?  If so, that is high!   :o
