That was a culture shock for me when I moved to the US. I knew that back in the day, in rural areas of my country, the markets only opened once a week. I was shocked to find that happen in urban/suburban areas in the US. Back home I could just go to the closest market any day. Morning news would have a report comparing prices in different markets across the city, so you could pick the one that has the best price for what you need that day.
