Where does the cost of products purchased as display items go for direct sales home party consultant? If I give a product as a hostess gift or prize, how do I report it?

This is my first year working as a Thirty-One Gifts direct sales home party consultant. I have purchased quite a few of their products to show at home parties and vendor events.  I don't know if I record them as Inventory or Promotional/Samples.  Also, what if I sell a product as "cash and carry" or give a product as a hostess gift or party prize?

Thank you for your assistance.
