Can I do the free trial if I live outside the United States?

Sorry, no. This is only eligible for US customers because shipping costs would get out of hand shipping back and forth all over the world. Plus, our shipping carrier does not allow us to create prepaid return labels internationally, so we could not do it if we wanted to! If you REALLY want to try them on first, email us and we can arrange it, but you will be responsible for shipping fees there and back to us! :)
