For you smart phone users out there, Apple has a new app coming soon called Cards that will turn your photos into letterpressed mailbox love. Similar to the postcard service I wrote about before, this app uses a picture from your phone, lets you choose a design and personalize the message, and then they print, stamp, and mail a physical card through the U.S. Postal Service. All for $2.99 within the U.S. and $4.99 international.
