The USPS has lumbered into the 21st century with just what you've always wanted.
Admit it, you've marveled at the lovely art work but really lusted for scratch-n-sniff stamps.
Well your prayers have been answered, June 20th the USPS will introduce these beauties.
They will all have the same smell, but what that is has not been released yet.
Waiting with abated breath.
