Emily Helwig Where I work we sometimes have minimum purchase requirements to receive free gifts or certain discounts. eg Spend $50 and get a free item. I have customers who have boldly told me to my face that they just wanted the free item and they plan on returning the items that they have purchased the next day. This is not only wrong but it also hurts our store's sales goal.
