How a cheap chicken can pay off without making money

A loss leader is an item sold at little or no profit—or even at a loss—to make the overall shopping trip more valuable to the seller. Costco’s rotisserie chicken works because the company is not judging the deal by the chicken’s margin alone. It is betting that the visit will lead to purchases whose combined profit outweighs the discount.

That bet depends on a familiar shopping pattern: once people are inside a warehouse, they may add items they had not planned to buy. A chicken can anchor the trip with a clear, appealing price, while the journey to it exposes shoppers to other merchandise. The effect is not guaranteed—some customers buy only the chicken—but even a modest increase in extra purchases can help offset the cost of the offer.

Why the strategy fits a warehouse club

Costco’s business also benefits when a low price gives members a reason to return. Membership fees provide revenue separate from the sale of any particular product, so the company can value a chicken partly for the visits and loyalty it encourages. That does not make losses irrelevant: the strategy works only if the broader economics of membership and shopping trips compensate for them.

The chicken’s location is therefore part of a larger retail calculation, not magic. It turns an everyday meal into a destination, then gives the store a chance to earn money elsewhere in the basket. The real product being promoted is the trip itself.
