This year only 10 addresses can be drawn on 1st October (World Postcard Day)
I think it is a good decision.
And so, to try to ensure that everyone can send a few postcards on that special day, we’re setting a limit of 10 postcards per account during October 1st . If you only have a couple of slots available, you’ll be able to send a couple of postcards. If you have 5, you can request 5 addresses. But if you have 10 or more slots available, you’ll only be able to send 10 postcards on October 1st.
