If you are going shopping the least you can do is "anunciar una liquidación". This can be used for a brand or shop to communicate that prices are reduced so that would not depend on the buyer. The rest of the sentences correspond to the one who is buying or wants to buy.
Ella ahorró dinero (she saved money)
Nosotros gastamos dinero en el supermercado (we spend money in the supermarket)
Tu trabajas? (Do you work?)
Ellos trabajan en el restaurante (they work at the restaurant)
Yo saco 100 del cajero automático (i took out 100 from the something)
C. proyectos I hope this helps
