Our question this week raises a shopping dilemma. You go shopping and see something you really like but the price tag is too much. How can you say it's too expensive without being rude or showing 'sour grapes'?
In this week's programme, Rob and Feifei try out some polite phrases at the Question and Answer department store.
Have a listen and see if you can use them. Plus find out what it means to sound like a 'sour grape'.
