Call to action based pizza ad:

In 1979, Jeno’s Pizza Rolls pulled off one clever marketing trick. They ran an ad asking people to write a letter for a free recipe booklet. But there was a catch: the mailing address was only printed on the pizza roll box.

Why it works

• You had to buy to get the reward (forced purchase).
• The “personal” letter request felt direct from Jeno himself.
• The freebie (recipe booklet) built brand loyalty.
• The scarcity of info (address only on box) drove action.

Examples

• Cracker Jack’s prize-in-the-box made people keep buying.
• McDonald’s Monopoly game requires purchases to play.
• Modern loyalty apps give bonuses only after scanning a receipt.

Old-school mail-in promos still teach one timeless rule: reward your buyers, not just your browsers.
