Until the end of August you can send postcards with Touchnote for free. Just upload your own image or use one of their Olympic themed pictures, write your message, enter an address and away you go!
The postcards and postage is totally free for a month so no excuse for slacking on the snail mail. Everyone loves to receive post in the mail so spread the joy today!
(I think the postcards probably arrive with the Samsung logo on them. I believe they are sponsoring this initiative so presumably there will be some corporate branding.)
