Convenience stores thrive on speed, traffic, and high-volume sales. But the products that sell the most are not always the ones generating the most profit.
In 2022 alone, U.S. convenience stores produced $302.9 billion in in-store sales, according to data from the National Association of Convenience Stores (NACS). Food, snacks, and beverages account for nearly 90% of in-store revenue, making them the backbone of c-store retail.
However, some of the biggest traffic drivers — like cigarettes — have relatively thin margins. Meanwhile, other products deliver much stronger returns by combining low product costs, fast turnover, and impulse purchasing behavior.
For operators looking to strengthen profitability, understanding which c-store categories have surprisingly high margins can make a meaningful difference to your bottom line without increasing foot traffic.
Here are seven c-store categories that consistently generate higher-than-expected returns.
Prepared food is one of the most profitable areas inside convenience stores, with average gross margins of about 55%. It also represents the largest share of foodservice sales, accounting for more than two-thirds of the category.
Hot items such as roller-grill snacks, breakfast sandwiches, and other ready-to-eat meals perform well because they provide quick, convenient options for commuters, shift workers, and travelers. Since many items are prepared in batches and sold throughout the day, stores can meet steady demand while keeping food costs relatively low.
Hot dispensed beverages account for about 9% of foodservice sales, and coffee dominates the category, representing more than 70% of those sales. Cappuccino and specialty coffee make up another 18%.
Many customers stop at the same convenience store every morning, creating a steady and predictable sales pattern. Loyalty programs and refill incentives can further encourage repeat visits while increasing the value of each purchase.
Cold dispensed beverages represent another c-store category with surprisingly high margins. In this segment, carbonated beverages account for more than half of sales, with fountain soda as the largest contributor.
These products benefit from the combination of convenience and customer habits. Fountain drinks are often purchased alongside hot food items, creating natural bundle opportunities during breakfast, lunch, and afternoon snack periods.
Because these beverages are self-serve and frequently paired with other purchases, they help increase transaction value while complementing other in-store food and snack sales.
Grab-and-go snacks remain one of the most dependable profit drivers in convenience retail. Categories like salty snacks and candy deliver strong returns while appealing to quick impulse purchases.
Industry data shows salty snacks carry a gross margin of nearly 40%, supported by year-over-year sales growth. Candy delivers one of the best yields among major merchandise categories, with margins over 50%.
These products succeed because they are natural add-ons to beverages and quick meals. Customers who purchase a drink often include chips or candy, increasing the average transaction with little extra effort.
Seasonal promotions and new flavor launches help sustain customer interest, keeping snack categories active year-round.
Packaged beverages are one of the most important profit drivers in convenience stores. In fact, they rank as the largest contributor to merchandise margins, with gross margins averaging nearly 43%.
Many retailers increase profitability by promoting private-label and value-priced drink options, such as store-brand bottled water or lower-cost soft drinks. These products typically cost less to source while still appealing to customers looking for convenient, ready-to-drink beverages.
Because they combine steady demand with healthy margins, packaged beverages remain one of the most dependable high-profit categories in convenience retail.
Lottery tickets themselves have slim margins, typically around 5–6%, but the purchases surrounding them often contribute more profit to the overall transaction. Research from NACS shows that about 95% of lottery customers purchase at least one additional item while in the store.
Customers buying lottery tickets frequently add small items while waiting in line. Candy, snacks, drinks, and other low-cost impulse products are placed near lottery terminals to encourage these quick add-on purchases.
Because many of these items already fall into high-margin categories, they can increase the value of lottery transactions without requiring additional marketing or promotion.
Individually, these purchases may seem minor. Across thousands of transactions, however, they can represent a significant share of overall store profitability.
General merchandise, such as phone chargers and small electronic accessories, often sells to meet immediate customer needs. Drivers and travelers often discover they need a charger or cable once they’re already on the road.
Because these products solve an urgent problem, customers are often less price-sensitive. This allows convenience stores to apply significant markups — sometimes exceeding 700% above wholesale cost.
Although these items represent a smaller share of total sales, they can still generate solid margins while fulfilling an important convenience need.
Industry benchmarks highlight common profit drivers, but every convenience store develops its own sales patterns. Identifying c-store categories with surprisingly high margins at your location requires sales data — and that’s where your point of sale (POS) system becomes essential.
