A Question for the @steemit community.

Is it appropriate to post items for sale on Hive account@steemit. I would like to keep all of my earnings from the sales on the platform. I am open to using an Escrow service to ensure safety of both parties, but would rather deal direct. This is what the post would look like and would include a short video description. This is just an example.
