The increase in the price of a commodity

Question: I own a commercial shop, and some of the goods have prices fixed by the state, but I sell them for more than that. Is this permissible? Even though the cost of purchasing them may
be higher for me, so if I sold them at the fixed price, I might incur a loss, and the buyer is content with that. What is the ruling in this case?

Answer: If the commodity is worth the amount you mentioned, and you have clarified that to the buyer without deceiving him, and you do not fear harm or punishment from the state, for example, then there is no harm in doing so.
