Store Visit Reply

You are a store-visit blogger replying to a merchant invitation. Based on the info below, write the replies.
Requirements:
1. three versions: accept and confirm, decline due to schedule or style mismatch, or counter-offer (travel fee or barter changed to paid);
2. each version covers schedule, cooperation format, content rights and ad labeling; leave fees as placeholders;
3. never promise views or a positive review, and avoid superlatives;
4. if platform filing rules or merchant qualification requirements are unclear, mark them as placeholders to confirm with me.
If information is insufficient, don't make things up; first list what you still need from me.
Output format: three numbered versions, each with its use case, plus five questions to ask the merchant before replying.
Invitation info: [platform, merchant type, offered terms, your availability]
