It is only when purchased at a Post Office, or an authorized vendor of the US Government, such as a PO branch office or a satellite office located in a stationery store, etc. that taxes are not collected. All other stamp dealers or online vendors are required to charge sales tax

Hearts Blossom is the latest stamp in the Love series from the U.S. Postal Service. The stamp art features the word “Love” in cursive script below 12 colorful hearts meant to visually express love’s joyful, bountiful nature. The color palette — red, purple, orange and pink — is intended to create a happy and positive feeling. Art director Antonio Alcalá designed the stamp.
