Every week a Guardian Money reader submits a question, and it's up to you to help him or her out – a selection of the best answers will appear in next Saturday's paper.
This week's question:
A friend has been giving me a hard time after seeing Israeli fruit in my home. (She also disapproves of me using supermarkets.) She's urging me to join a consumer boycott, but I don't think these work. Leaving aside the issues, do these campaigns really make a difference?
What are your thoughts?
