Gmail is dead serious about making their own stickers, and like any good geek, I started freaking out about how much I wanted these immediately.
But, as we already know, Google is a fair and lovely company, and has made it easy for you to get your own. No, there's no online order form, you just have to send a self-addressed stamped envelope (remember those?!) to:
Send me some Gmail stickers already
P.O. Box 391420
Mountain View, CA 94039-1420
Better send it in soon, because you know those will not last. Oh, and my fave is definitely the Gmail m-velope.
