The return of BTS has generated a significant boost in sales for convenience stores located in Gwanghwamun, where their comeback concert took place. Reports indicate that on the day of the concert, the sales of various food items such as bottled water, ramen, kimbap, and sandwiches saw a remarkable increase, along with practical goods like batteries and hot packs. For example, BGF Retail, which operates the CU convenience store chain, reported a staggering 270.9% increase in sales at ten stores nearby compared to the previous week, with some stores closest to the concert venue experiencing sales boosts of up to 547.8%.

The BTS effect was not limited to Gwanghwamun; it also extended to tourist hotspots like Myeongdong. Various stores in these areas showcased purple decorations in honor of the group's color, and some provided discounts to customers displaying purple items. Staff in certain stores have noticed a clear uptick in foreign tourists as the concert approached, which suggests a broader revival in local shopping activity linked to BTS's popularity. However, not all retailers reported the expected benefits, as some expressed that sales did not quite meet their expectations, highlighting the unpredictable nature of such event-driven consumer behavior.

In conclusion, while the BTS comeback concert did lead to significant local economic activity, the overall response varied among retailers, indicating that despite the excitement created, not all areas benefited equally. The influx of tourists and fans surrounding the event showcases the powerful impact of pop culture on local economies, and the necessity for retailers to adapt to fluctuating demand patterns tied to such events.
