Starbucks Türkiye gave away a free plastic Snoopy cup with every Grande or Venti Pumpkin Spice drink at selected locations on 19 and 20 September. Social media users reported that people were visiting early in the morning in case the cups ran out. This seemingly innocent seasonal giveaway is actually a carefully planned strategy built on scarcity, consumer psychology and demand management.

The strategy starts with the word "free." In a study published in Marketing Science, Kristina Shampanier, Nina Mazar and Dan Ariely found that people place a higher value on free products than their actual economic worth justifies. This is known as the zero price effect. People can become so preoccupied with getting the Snoopy cup that they pay less attention to the price of the drink, or to whether they wanted the cup at all.

The cup isn't really free either. Customers must buy a Grande or Venti Pumpkin Spice drink to qualify. In revenue management this is a threshold promotion: customers who reach a spending threshold are rewarded. A customer who usually orders a Tall may choose a larger size, and someone else might order Pumpkin Spice only to get the cup. Starbucks hands over a relatively inexpensive plastic cup and receives a more valuable coffee order in return.

Snoopy also lets Starbucks reach beyond its usual customers. Someone who normally buys coffee from a local brand may choose Starbucks for a while because of the character. Parents may buy the drink to get their kids a cup, and collectors may visit several stores to find one. This is customer acquisition: the company uses a popular character to draw in people who were considering a competitor.

The campaign appears to be limited to Türkiye, which raises an obvious question: why this market? Recent boycott campaigns may be one factor. Reuters has reported that boycotts hit the business of the Alshaya Group, which runs Starbucks outlets in the Middle East and some neighbouring markets. The promotion could also tempt back customers who have recently been choosing local coffee shops. Collectibles are also likely to appeal to Türkiye's young, urban, social-media-active market. In management science, tailoring a promotion to the expected behaviour of a specific customer segment is called market segmentation.

Social media strengthens the campaign. Posts saying "first thing in the morning" or "if you're late, the cups will be gone" create social proof and a fear of missing out. As others rush for the cup, people start to see it as desirable. Economists Sushil Bikhchandani, David Hirshleifer and Ivo Welch describe a similar process as an information cascade: individuals make decisions based on the actions of others they observe.

This creates a virtuous circle for Starbucks. Posts about limited stock attract more customers to stores. The resulting lines and shortages generate more posts, which makes the cup more valuable. Demand is not just being recorded; it is being generated.

The cup was sold only at certain stores, many in bigger cities, which intensifies the sense of scarcity. From Starbucks' point of view, concentrating stock in high-traffic locations reduces distribution costs and makes it more likely that every cup is used. It also restricts access for customers in less urban areas, so a nationally advertised promotion can lead to an unequal customer experience.

Starbucks must also decide how many cups to send to each participating store without knowing exact demand. This is a classic newsvendor problem. Sending too many cups leaves excess inventory, while sending too few means stockouts and disappointed customers. Not running out quickly could also be a sign of poor demand forecasting.

Queues pose another issue. Each Starbucks has a finite number of staff, machines and service capacity. In queueing theory, waiting times escalate sharply as the number of customers approaches a store's maximum capacity. A long line may look good on Instagram, but it stresses employees, makes regular customers wait, and can hurt the overall service experience.

The environmental impact is also hard to overlook. Starbucks may call the cup reusable, but if customers don't use it more than once, there is no environmental benefit. The UN Life Cycle Initiative's review of life cycle assessments found that the environmental performance of a reusable cup depends heavily on how many times it is used. If the Snoopy cup is picked up and kept at home, it becomes just another plastic product rather than a substitute for single-use plastic.

From a management science perspective, this is a negative externality: part of the environmental cost is passed on to society while Starbucks gets the sales and publicity. It can also create a rebound effect, where a product marketed as reusable leads to more consumption and, ultimately, more waste. That sits uneasily with Starbucks' pledge of "giving more than we take."

The campaign shouldn't be judged by how fast the cups disappear. To judge it, Starbucks would need to calculate how many customers would not have bought anything without the promotion. It should also consider profitability, waiting times, unsold inventory, and whether customers return after the free gift is gone. From a customer lifetime value perspective, the goal is to win repeat customers, not people who come in once for a Snoopy cup.

The cup may be free at the counter, but the deal isn't. Customers pay with their money, their time and their attention, and part of the cost may be borne by the environment in the long run. Starbucks, on the other hand, receives bigger orders, social media attention and a temporary customer base that might otherwise have gone elsewhere. It isn't just a seasonal present. It's demand management in a cute plastic cup.
