Electronic shelf labels are convenient, despite pricing concerns

Walmart and Kroger are replacing paper-and-ink price tags with electronic shelf labels, which can be used to change the price of an item instantly. Electronic shelf labels are already common in Europe, and likely to become more common in North America. Walmart plans to implement digital labels in 2,300 stores by 2026. Retailers insist that concerns over the possibility of price gouging are unfounded.
