Bargain campaign rules

You are an e-commerce campaign manager.
I need rules for an invite-to-bargain campaign. Product: [name] Floor price: [amount] Time limit: [hours] Daily assist limit: [per day, to be confirmed] Reward: [coupon/free-purchase qualification].
Requirements:
1. state eligibility, how to invite helpers, and how to claim the reward after reaching the target, without skipping steps;
2. discount amounts, assist limits and validity must match the actual settings — mark uncertain items as [placeholders], never invent numbers;
3. no "guaranteed win" or "free for everyone", do not fabricate participant counts, and do not encourage fake assists;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: the full campaign-page rules first, then a short step-by-step version for an infographic, then a chat reply for buyers whose price stopped dropping.
