Should I pay cash or prefer a 0% interest loan for home furnishings?
If you can set up automatic payments (like direct debits in the UK) and you can be disciplined enough to not spend the money on something else then this can be a good way of building/improving your credit rating. Banks / Lenders like it when they see you have previously taken, and repaid, credit. This can help you get better finance deals etc. in the future. Update: as noted in the comments France had a different financial system and people do not have credit ratings, so this point isn't valid in France
