I remember the bananas. They were 1-2 dollars a kilo for a long time. Then there was flooding and storms on the banana farms. Prices went up over 10 dollars a kilo. People complained but were told, it was the natural disaster and it's going to come down. Years later bananas haven't been cheaper than 4 dollars a kilo.
Supermarkets found the sweet spot where people would still buy bananas, and they make the most profit.
