You’d think that, but it is not. I buy 12oz bags of coffee. Alcohol is also sold in both fl oz and ml, so a bottle of beer is 12oz, and a bottle of booze is 750ml.
Hmm ok, well apparently 12oz is 340g, we’d never see coffee sold in that weight. Normally 200g (7oz), 500g (17.6oz, 1.1lb), or 1kg (35oz, 2.2lb). The one linked is a bit smaller than standard at 180g (6.3oz).
Yeah, that is pretty small and very expensive. Around Seattle I pay $15-$20 for a 12oz (340g) bag of specialty coffee
A more typical price here would be say $15NZD - $20NZD for a 250g bag (and slightly cheaper per g for larger bags).
$20NZD is about $12USD, and 250g about 7oz, so scaling up that makes it about $20USD for 12oz (including tax), so same ballpark! Honestly, I’m surprised. Normally stuff is more expensive here
