You'd think that this would be the fairest way to price,

Not necessarily. What it cost them in the past is just that: the past.
I would expect them to price it at whatever it's worth right now.

That means if they bought it cheap and are making a hefty profit, I'm
OK with that. It would be nice for them to share their luck with me,
but I don't expect them to since they're a business. On the other
side of the coin, I don't expect them to charge a lot for it if they
bought it when prices were high but prices have dropped a lot since
them. That's their problem in exactly the same way that it's their
good fortune if they managed to buy low and sell high.
