Is it legal in Washington state for someone to give items to a minor that you have not requested that require you to purchase or return them?

The company that takes photos for my daughter''s school prints copies even if you do not order and has the school send them home with children (as young as five years old). If you do not return them you are required to purchase them, I assume that they would require you to pay even if you did not receive the photos from your child. I do not think this is right and would like to know for sure if this is even legal. Thank you for your time.
