Okay, the user wants me to translate "extra costs" into French. Let me check the rules again. The first rule says to translate all content into French. The second rule states that if the content is already in French, leave it as is. The third rule is to provide only the translation without any explanations.
So, "extra costs" in French would be "frais supplémentaires". I need to make sure there's no explanation, just the translation. The user also mentioned that for each message, I should respond with just the translation. Let me confirm that "frais supplémentaires" is the correct term. Yes, that's the standard translation for extra costs in a formal context. No need to add anything else. Just output the French phrase.
frais supplémentaires
