Retail sales in Mexico are dominated by major chains like Walmart de México (over 66% of supermarket sales), as well as other large players such as Grupo Chedraui, Soriana, and La Comer. That said, the market remains relatively fragmented, with a mix of hypermarkets, discount stores, cash-and-carry outlets, convenience stores, pharmacies, and smaller independent retailers. As a result, the Mexican POS terminal market is driven by the larger retailers, but remains less mature in the more rural areas.
