I have a request like this. We will write the cost for product X on the site and determine a 20 percent or 50 percent sales price for its sale.
For example, we will write the cost of a product with a cost of 10 TL as 10 TL. We will choose a percentage (20% or 30%) and sell it for 12-13 TL. Is this possible? Frankly, I do not want to do this with an additional plugin.
