Up here north of the border, food (along with everything else) on the west coast in BC tends to be slightly more expensive than it is in e.g. Ontario. This is an interesting site, would love a Cannuck version.
It'd be interesting to evaluate this because unlike iPhone, fruit can trivially be substituted. In other words: the margins on them are what capitalism predicts: essentially nothing. This even goes for the aldi store as a whole.
It does not apply to specialist medicine, and only to a very limited extent to Apple products. So Apple can "enshittify": extract the maximum the market is willing to bear. They can steer demand. Aldi cannot.
