Is it ethical to sell gift items, like free event heads, or free dolls? What about a doll which comes with two heads? Should the seller only sell the extra parts at the price the item would usually sell for, or accept higher amounts? Is this a concern for free gifts that are not dolls, such as clothing, and if not, why the double standard? What about someone who uses a free item to make something new, such as a complete doll out of a free head or a new outfit with a free clothing item?
