The big market though seems to be in plants and in particular orchids.
Some of the plants were arranged in containers but many looked like that they had been hacked out of the ground that morning. I am really not sure what the ethics of buying plants like this is; you decide for yourself I guess.
I was told that the best time to buy is in the afternoon shortly before the stall owners need to shut up and head back over the border, they obviously don't want to carry a lot of stock back with them.
I didn't get into asking about prices as there is no point in haggling over something I have no intention of buying but 20B for an orchid was being freely offered as I walked around.
