When don't you have to stick a stamp?
Received a nice post, it used to happen daily, or at least weekly. When the mailman came down the street, you were already looking forward to what he came to bring. Nowadays we receive few nice letters or postcards in our mailbox. Writing a real letter with pen and paper and sending it, we almost don't know that anymore. A real shame!

If you have to send out something, that's often a little thing. Are you confused? What format may or should the letter be? How many stamps should be on? That's of course just check at PostNL, you'll find the current postal rates. HERE .
Sending a letter costs quite a bit these days. If you don't HAVE to stick a stamp, then of course you don't! But when does it not have to?
Mail to a answer number you never have to post. So you don't have to put a stamp on it! You don't have to write anything with it either. The recipient pays the stamp, sending them letters to a reply number for you, so completely free of charge.
