If the price of oil decreases, it would most likely cause the price of your product to decrease as well, all other things being equal. This is because a decrease in the price of oil would result in lower transportation costs for your business, which would lower the total cost of producing and delivering your product to stores. As a result, you would have the option to either pass on the cost savings to your customers by lowering the price of your product or maintain the same price and increase your profit margin. However, if there are other factors that increase the cost of producing your product, such as an increase in the cost of raw materials, labor, or taxes, then the price of your product may not decrease despite the decrease in the price of oil.
