Here the seller sets the prices for the goods. Do you have the opposite?
I think you'll find in the real world it is the customer that is king. Maybe you have never heard of supply and demand. If the goods or services you provide are too expensive or controversial people are free to find an alternative, buy less or don't buy at all. Their market value is what people are prepared to pay.
We have the current market rate for a barrel of oil and taking Russian oil as an example nobody is going to pay Russia the market rate due to the circumstances. Countries who decide to do business with Russia will take advantage of this and trading will be substantially lower than the market rate or they will not buy.
As time goes on and the world adjusts things will only get worse for the fatherland. In the meantime i would be wondering if the seller is setting the price for the goods. Do we have the opposite?
