There is still the big market in the city center, but it just the same 7 or 8 things sold by countless people. There is no more variety there than anywhere else in the country. Usually things are only a few cents cheaper there, so it only makes sense to travel there if you have a car and a big fridge, and can buy enough stuff to offset the fuel costs.
For us, a family of 4 with a bicycle, travel to downtown and back is about a 3-hour round trip, and I'm usually so tired when I get back that I usually don't work that day, and that causes a loss of $20 or more. There are about 10 fruits here commonly sold, but all were too expensive for us to purchase, even before the economic crisis and pandemic.
We are located in the far north, a bedroom community on the riverside near where it meets the ocean water.
