UK's somewhere in the middle - few people would pay £20 for a zine and would laugh at the price but they /might/ buy a cool piece of art for that price.
At the anarchist bookshop £20 would get you some full size book on praxis (maybe even in French or German), although that was almost 40 years ago! they did also sell some alternative publications at slightly higher prices but those were more like books than zines (and still more than a teenager could afford)
That said, I've not seen a zine fest in my region since I moved here 20 years ago. I did find some zines (presumably published in London?) going for higher prices, but they've all got online shops, even with Klarna!
