Trailer item reminding people to put the correct postage stamps on letters before posting.
Postage stamp revenue - trailer.
Several shots of people posting letters into post boxes. M/S of woman posting letter. The commentator asks the women, "but that letter's going abroad. Have you put the right stamp on it ?"
The woman looks slightly confused. She stands next to the letter box and her envelope comes back out of the slot. She looks carefully at the stamp o the envelope. C/U of the envelope which is addressed to France. The commentator gives the correct amount of money that should be paid on letters weighing under 1 oz (four pence) and over (two and half pence for each additional oz).
