Show Who purchased a product

I am implementing opencart and needed a function that is if it exists.
Is that you can view a list of products sold and at what price they were sold. That is, q going to each product that was sold, a list of buyers of that product and at what price they bought it (because some of us may have bought on sale and some not).
Do not know if there is a module for this, and if there is not, someone can give me an idea how I can do this ...?
Thanks

Just query the order_product table based on the product id. They will show the correct prices in there
