"There's a way to do it electronically - uh, over the computer - but there's also physical currency and it's arguably safer to stick to that. You will have to pay for almost everything, other than food and housing. Well, the housing comes with water and wifi, too. And sometimes you can get old clothes for free if people are giving them away. You, uh... do work for people, and then they give you money. There are websites for finding work, you can look them up later, but basically if you agree to an hourly rate it usually shouldn't be less than two silver - they're not made of silver but that's what they're called. In the older parts of town people are more likely to haggle when they're buying things, especially at one of the outdoor markets. That happens less in some of the newer neighborhoods and pretty rarely if you're buying online. And taxes exist, there are taxes on, uh... buildings, but you won't be owning one so it won't matter to you, and cosmetic surgery, and sales taxes on, lemme look it up... incense, silk, cotton, perfume, gold and silver jewelry, gold and silver drinking vessels, Tyrian purple, indigo, cars, gasoline, coal, computer games, live animals, plastic objects, habit-forming psychoactive substances, and inhaled substances likely to be offensive to neighbors. The responsibility for those is on the person selling things, so you have to worry about that if you're selling but not if you're shopping. And that's... pretty much everything, I think?"
