You pay today's price. Transparently, this is just the dollar price from the distributor, converted to sats at the current USD/BTC price.

I include the "last year" and "2020" for fun, to give a sense of what it might look like to live in a deflationary world. The same sats go further all the time.

I will likely add a "hide this junk" option in the future if people complain about it.
