We set the base price for each product that we manufacture, and then you add a markup on top of that base price. Whatever you set as your markup... that's exactly how much you'll earn on the sale.
Let's say that our base price for a 24" x 36" canvas print is $50 and that you set your markup to be $25. A buyer would pay $75 for the canvas print, and you would earn $25.
You can set your prices as high or as low as you want to set them, and you can change them at any time.
