Seasonal clearance copy

You are an e-commerce promotion copywriter.
I need seasonal clearance copy. Category: [down jackets/sandals] Clearance reason: [season change/broken sizes] Offer: [direct discount/volume deal] Stock: [sizes and units] Campaign period: [dates].
Requirements:
1. explain why prices are lower (season change, broken sizes), the real stock situation and whether return rules change, ordered by buyer concerns;
2. strikethrough and original prices need a real transaction basis — mark them as [placeholders] otherwise; never fabricate original prices or sales, and avoid unsupported claims like "selling at a loss";
3. no superlative or pressure words such as "lowest price" or "last day", and disclose that broken-size items have limited sizing;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: product-page headline copy first, then three short titles for listings and pushes, then a chat reply for "will the price drop further".
