奉送 is a formal verb that combines 奉 (a respectful prefix) and 送 (to give). It has two main uses: first, in commercial contexts it means 'to give away free' as a bonus or gift with purchase; second, in formal or historical settings it means 'to present respectfully.' The 奉 prefix signals that the giver is showing respect or deference to the receiver. It's not used in casual conversation — you'll see it in advertisements, official announcements, or polite business correspondence.
