Even our currency is very unstable against other dominant currencies so consumables are equally expected to be unstable. We here pretend to be developing a taste for our own products which we have the resources to produce. What surprises me is the fact that we still import common vegetables like tomatoes.
If we are so worried about prices of commodities like food going up, why don't we plat our own food, make a self sustaining garden to meet the daily needs, it can greatly cut your expenses because you don't need a lot of things to buy when you go to the market. I don't know the reason for your country to import tomatoes but maybe there is a shortage in the local supply or your country has an agreement with the other countries regarding imports.
