So far, the most expensive commodity today is the tomato; last week it was around 1.75$ per kilo, but now it has increased too much; it hurts the pocket, honestly speaking, because it is now at the price of 2.3$ per kilo, followed by potatoes, which last week were around 1.9$ per kilo and are now at a price of 1.8$ per kilo.
Although the others have gone down, they can still be considered expensive. That's why we can't do anything; we really have to survive and find a way to get a source instead of complaining and stressing.
