@WikiPim, No you don't understand what he is trying to say. Assuming that price only matters a little bit, it's better trying to sell an expensive item, because you get more money if you succeed.

For example, let's say you could sell a leather shield for 400 with a 50% chance of success, or a copper shield for 800 with a 40% chance of success. The "expected value" of the leather shield is 200 (400*50%) while the expected value of the copper shield is 320 (800 * 40%). So even though you sell the copper shields less frequently, they will bring more money over the long run.
