This is exciting as heck... the United States Postal Service has announced that they're releasing an official Harry Potter Forever Stamp on November 19, just in time for the holidays!
I have no doubt that Orlando's Wizarding World amusement park will be one of the post office locations selected to distribute them on the first day, but I'm not going to head there just to get my owl post stamped with a First-Day-Of-Issue postmark.
They'll make a great stocking stuffer at $9.20 for a booklet of 20 stamps, too.
Initially, only 3,100 "Premier Post Offices" will be receiving the stamps; the USPS will roll out the Harry Potter stamps to other post offices at some point in December.
