Sometimes I have troubles to send a postcard, note, greeting or a thank you card. Well, email is the salvation, but what to do if the recipient is not connected or have no internet access, it takes ages to organise all the preparations - the card, stamps, etc., and finally to post it.
I propose an organisation that will take care of all this. Sender would contact them by email, and they would send a printed copy to recipient. The only problems are with advertising service and method of payment.
