decades ago there was a story, how the shelves at aldi looked cheaper, but where actually more expensive, and just gave the impression of looking cheap. in hindsight, i now think that while true, those shelves are probably also more efficient to use (allowing them to put up products in their boxes, hold more weight, etc)

aldi was also selling products for less than what they paid for. this is common practice in some places but in germany it's actually illegal, and they had to stop that.
