Peanut butter costs twice as much in a jar half as big here. So it's quadruple the price, twice as expensive as fucking geniune Nutella (of which this is an ersatz), actually.
PB has always been a luxury, novelty product around these parts. It's not ingrained in our diet, we are not used to it, and it feels weird to put it on bread. Last time I tried it was some 20 years ago, when my parenents bought it out of curiosity, and I remember it being difficult to even swallow because it'd just stick to your throat, teeth and tongue like glue. It's not bad, we'd just rather have something else. PBJ as a concept in general feels like something an alien would make. It's still miles better than filth like vegemite or marmite, though. That shit is vile. Tried it once, had to rinse my mouth with vodka.
