As inflation and shrinkflation reshape America's dining landscape, consumer behavior shows diners are seeking deals at an unprecedented rate. Fast-food chain Carl's Jr. is responding to this demand with its new Cali XL burger, offering guests double the beef of the Big Mac, verified by independent and internal experts, alongside a "Sad Mac Buy Back" campaign.

"People want a burger that's actually worth it. Our new Cali XL has more meat, more flavor and more value," said Paz Romero, vice president of brand at Carl's Jr. "The 'Sad Mac Buy Back' is our way of letting guests try it for themselves by swapping disappointment for something better— no questions asked."

Sad Mac Buy Back: Burger swap

From Nov. 12-21, 2025, Carl's Jr. is inviting consumers to swap their old Golden Arches receipt a free Cali XL burger loaded directly into their Carl's Jr. rewards account.

More value."
