Thr bookmark is light enough I would expect you could send it cheaper on its own, but the DVD would qualify for media mail.

You aren't allowed to add "incidental items" that are not media, so it would fail from that, but I bet most postal inspectors would not fault this because of a bookmark. It looks like a little "free gift" that some vendors give you, like a packet of gummy bears.

It's pretty funny that the seller flipped it around.
