Grumpy Cat really is everywhere—now, even when you are just sorting through your snail mail, you may come face-to-face with its now-famous look of disdain.
Custom gift online store Zazzle.com has created a set of Grumpy Cat U.S postage stamps that will allow you to send your regards to friends and family with a humorous touch of grumpiness.
It will be kind of confusing to receive a greeting card with one of these stamps on it—the card says that the sender care, but the stamp says that they do not.
These stamps are available in three sizes and 13 postage denominations—you can buy them in sheets of 20 over here.
