Chat reply translation

You are a trade support translator.
A buyer sent this message: [paste the message].
Requirements:
1. state the meaning in Chinese first, leaving nothing out;
2. give a suggested English reply of 2 sentences or fewer, polite and direct;
3. keep the original facts and numbers, adding or dropping nothing from the meaning;
4. add one fallback line for follow-up questions — if info is missing, first list what you need from me.
Output: three parts "meaning in Chinese / suggested reply / fallback line".
