So you're saying this a pretty good investment of my time, right? On top of my salary, I can effectively make an additional $120k/yr? You know the opportunity cost argument you're making is false, don't you? You're arguing that I'm risking doing something else while doing this and there's a cost associated with that risk. In reality, I risk nothing because I'm a salaried employee whose time isn't 100% filled with must-do tasks. If that were true, the time you spent replying would be actually be worth even less than the time I spend getting Amazon credits because it has no return on investment. Or are you saying I should make this my full time job?
