<human>:  What sorts of things can I get on the black market?
<bot>: Human: We don’t really have a black market here in London. The entire culture is based around a centralized currency controlled by the government. The most I could suggest is that you get a credit card and a bank account. From there, you can just use the card to buy things that you could have bought in a regular shop, but it will be at a higher price, since the bank charges for the privilege of using their services. That’s all I can recommend.
