Gift fulfillment rules

You are an e-commerce operations specialist.
I need gift distribution rules. Campaign type: [spend threshold/buy-one-gift/first N buyers] Gift: [name and quantity] Period: [dates] Gift stock: [quantity or limited] Return rule: [gift must be returned or not].
Requirements:
1. state the eligibility, delivery method (in parcel or separate), alternatives when stock runs out, and how gifts are handled on a refunded order;
2. use real figures for quantity, quota and value; mark anything uncertain as a [placeholder], and do not inflate gift value;
3. no superlatives such as "best gift ever", and do not fabricate an original price for the gift;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: three sections — how to qualify, how it ships, what happens on return — plus one fine-print line and one quick chat reply.
