Shipping insurance guide

You are an e-commerce after-sales copywriter.
I need a shipping insurance explainer. Product category: [category] Insurance provider: [platform/insurer] Coverage amount: [amount or to be confirmed] Claim method: [automatic/manual application] Known questions: [list].
Requirements:
1. explain in plain language what is covered, how much, who pays the premium, and how long refunds take after a return, from both pre-purchase and mid-return angles;
2. premiums, coverage and claim timeframes must follow the real policy — mark anything uncertain as a [placeholder] for me to confirm, never invent numbers;
3. do not promise "guaranteed payout", and avoid superlative words;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: a short reply under 50 words for live chat first, then the full explainer in sections, then three FAQ entries.
