The printer says that they'll have FreeBSD Mastery: ZFS to me before I leave for BSDCan.

And they've sent UPS tracking numbers. Numbers that UPS acknowledges. While they don't show a delivery date yet, UPS says that the boxes exist.

So I'm pretty confident in saying that I'll have books there. And I take Square.

The list price is $24.99 US. Given the exchange rate, they'll be $25 USD/$30 CAD for a "FreeBSD Mastery: ZFS" print/ebook bundle.
