Lotte Mart Zetta said on the 15th that it will run the seasonal food campaign "In season, Zetta watermelon fest" through the 27th.
Lotte Mart Zetta selected watermelon as the flagship item for May's "In season, Zetta." Because watermelon is a relatively high-priced fruit, consumers are known to scrutinize its sweetness and quality.
Accordingly, Lotte Mart Zetta is providing information that helps judge taste and quality—such as varietal characteristics including tiger-striped and black-skinned watermelons, Brix, origin, and quality inspection standards—so customers can choose watermelons with greater confidence.
Quality control has also been strengthened. Lotte Mart Zetta will offer all watermelons sold in this event as high-sugar products with at least 11 Brix. In addition, by using an AI sorting system, it reduced the likelihood of overripe fruit or hollowness (fruit whose flesh is not fully filled).
During the event period, Lotte Mart Zetta will offer a 1,000 won discount when paying with an event card on all watermelon items. On the 20th, L.Point members will receive an additional 3,000 won discount.
Meanwhile, Lotte Mart Zetta has been running the monthly seasonal food campaign "In season, Zetta" since Oct. 2025, starting with sweet potatoes as the first campaign item. Fresh MDs handpick seasonal products and provide origin information and selection criteria to introduce consumers to "the most delicious seasonal foods right now."
Lotte Mart Zetta has introduced a total of eight seasonal fresh food items so far. An analysis of sales during each event period found that average sales for the eight items rose about 70% from a year earlier.
Choi Ji-young, head of online marketing for Lotte Mart and Lotte Super, said, "'In season, Zetta' is a campaign designed to help customers buy seasonal foods with confidence, based on Lotte Mart's competitiveness in fresh foods," adding, "We will continue to offer a variety of benefits and shopping experiences centered on seasonal fresh foods to raise customer satisfaction."
