Is this the United States Post Office increasing sales by partnering with OEM greeting card makers, or Hallmark accessorizing base model cards with desirable add-ons? It is a near-perfect alliance no matter who crafted the treaty. Do see the joint logo sponsorship. This idea has been around for a while but I do not see it continuously at my favorite card stores. And when I do, usually the greeting category is limited and quite focused. I do carry many cards home by hand to my wife. But if they all had stamps, I would delight in easily mailing and surprising her all the more with postman hand delivery. Particularly if the postman cute and male to brighten her day further. If the concept catches on however, could we please have a outbound mailbox at the store exit. There are so few on street corners these days.
