Omo this issue is a big challenge in Nigeria,Nigeria need to try create a bench mark,which help to regulate prices of things been sold.but looking at the system those companies and industries own are still by the Nigerian politicians who benefit from it increase in price of goods in the market.
The market is likely manipulated by those in power for their own selfish interests. The regulation of price movement should be based on the bodies responsible for the food, don't ever underestimate the top tasks placed on these bodies although most of them have failed to deliver their jobs. Nigeria have failed to improve and have become dormant over the years, really devastating to watch the youths suffered and having zero positivity and balance in the country's economy.
