Don't you love a love stamp? Little pieces of art that dress up the commonplace, utilitarian envelope. To possibly say what you may be too reserved or just plain scared out of your wits to say on the note inside? They're relatively inexpensive, as well: a mere 42¢ for a first class send-off. Regardless of postage, wouldn't each valentine mailed technically be a special delivery? And is it true that if you affix any kind of stamp upside down, be it hearts or flowers or Elvis, that it means 'I love you?' Such are the mysteries of the month of love.
