The Seattlepi [1] reports that the Star Wars droid R2-D2 has a new job - to collect mail.

The post office is wrapping mail collection boxes in some 200 cities nationwide in a special covering to look like R2-D2.
It's part of a promotion for a new stamp to be announced March 28, said Anita T. Bizzotto, the post office's chief marketing officer.
"It's a little teaser for the upcoming announcement and we decided to have a little fun with it," she said.

Now watch out for star wars fans stealing mailboxes. ;)
