It’s a simple process:
Send in a self-addressed stamped envelope, get back some free Gmail stickers.
And why not. Pretty much anyone can get a gmail account these days, but not anyone will have a chance to get these stickers.
Send in your envelope, postmarked by February 14th, 2009, to: Send me some Gmail stickers already, P.O. Box 391420, Mountain View, CA 94039-1420
“Make sure to include enough postage to return a sticker pack via U.S. mail. It’s less than one ounce, so a standard $0.42 stamp will do if you’re in the United States; enclose an international reply coupon (IRC) if you’re outside of the U.S. ”
