It is currently available (and in stock) from the official resellers, at least here in Europe. Limited to one per order but that kind of makes sense considering the global chip shortage. Get one while you can. :)
Good news: in stock including US shipping at https://shop.pimoroni.com/products/raspberry-pi-zero-2-w for less than $25. Probably cheaper from US resellers but I'll leave that to you. Yes, one per customer, which is a reasonable policy right now.
I understand it's a global chip shortage, but when zero W came out, there wasn't one.
