I will send one from Thailand and one from Vietnam. Until when do we have? Also, there are some great apps which allow you to send postcards made from photos on your phone, so if you were in an exotic location and you took a photo of something on your phone, see if you can download the app and send it straight from there. You pay with your card and they even go to the post office for you...
EDIT: Postcards sent! Hope they get there safely.
