Ordering these things - or, at least, trying to - is beyond ridiculous now. I've been checking three or four sites every month or so for literal years now to no avail.

I've even tried shimmying in an order with an 'educational supplier' here in the UK who apparently have 'some', but only for schools, so they won't let me have one, despite how much material I buy from them each month for my non-educational purposes. I don't blame them, of course, but I do find it weird how there's apparently a heckload of demand and no uptick in production.
