In reply to Edgar (aka MrConsumer).

As you noted in the article, people still do have to pay for the free entry via the cost of postage. You should be able to walk into a Domino's and fill out an entry for free.

McDonald's really bugged me that they included the Monopoly game pieces on select food containers. Someone could go in there, order food, and get zero game pieces. That was encouraging people to pay to play. A co-worked would give me his french fries because he didn't like french fries. When I asked why he bought them, he said he did it for the game pieces.
