Below you'll find two videos related to the topic of "money." The first one is short and just contains explanations on the meaning of one vocabulary item. As for the second one, I have included in the comments section some expressions from it that you should look at and try to remember before viewing it. Once you've done that, I would like you to explain in a comment what the man has done to make some extra money and what you think about it. Is his advice useful? Would you consider doing the same as he did?
