Just left the post office and they had a small display on the counter with free postcards of Spongebob and Patrick. They are there to encourage children to write. They are also free to mail.

There were two different ones available. Not sure if there are more than that.

Was back at the post office yesterday and they were all gone. Hope if you wanted one you got them.

If not I grabbed one of each when I was there last time if anyone wants to trade.
