FOODCostco’s Spring Lineup Has a Side Most People Miss6 min read

Kirkland’s New Energy Drink and the Celsius Comparison

One of the more talked-about new items this spring is a Kirkland Signature Sparkling Energy Drink, currently available in three flavors: orange, tropical, and peach. The product is new to Costco’s lineup, and shoppers have been quick to draw comparisons to Celsius, the performance energy drink brand that has seen significant mainstream growth over the past few years. Celsius is widely sold at Costco, so the introduction of a Kirkland Signature alternative in a similar format follows the warehouse model of offering a private-label option alongside established national brands. The flavor profiles — citrus, tropical fruit, and stone fruit — align with the kinds of light, refreshing energy drink profiles that have driven category growth. Whether the formulation mirrors Celsius in terms of active ingredients isn’t confirmed from available shopper reports, but the positioning and format suggest it’s aimed at the same consumer. At Kirkland Signature pricing, the cost per can will almost certainly be lower than the branded equivalent.

How Costco’s Limited Availability Model Shapes Buying Behavior

Understanding why certain Costco items generate urgency requires understanding how the store manages its product catalog. Unlike traditional grocery stores that restock the same SKUs continuously, Costco operates with a curated, rotating selection. Items that perform well may return in future seasons; items that don’t may disappear permanently. This model — sometimes called the treasure hunt format — creates a buying dynamic where shoppers who see a desirable item feel genuine pressure to purchase it on the spot rather than waiting. The spring items described here fit this pattern: the Tiramisu Cheesecake, Crab Cakes, and Tru Fru strawberries are all seasonal or limited-run additions, not permanent fixtures. The Kirkland Sparkling Energy Drink is described as brand new, which means its shelf life in the rotation is still unknown. For shoppers who find value in any of these products, the standard Costco advice applies — when you see it, that’s the time to buy it.
