After the European Court ruled on 14 January 2010 that "a local law cannot prohibit, whatever are the circumstances, commercial practices consisting in making the entrance to a prize draw conditional on the prior purchase of a good or service, even if it is to ensure a higher level of protection of the consumer", France has finally relaxed their laws relating to promotions that offer a chance of winning a prize. I’m not a lawyer, so I strongly recommend reading the article about the changes in French law on the Marketing Law blog.
