The subscription process is very simple. You just have to fill in an order form at our Website HAPPY MAIL page, once a NEW theme is announced and voilá! You're good to go! We don't provide a continuous subscription option; so, you have to fill up a separate form for a new subscription. Boxes are in limited quantity; so, all bookings will be on first come first serve basis; so, it's better not to take chances and, to subscribe as soon as we announce the theme!
