The Etla market is a relatively small market near the center of Villa de Etla. The market is similar to most other markets in Oaxaca. Etla has its market day ( Plaza Day ) on Wednesdays, when the streets are filled with vendors in an authentic style of a traditional tianguis.

In the municipal market of Villa de Etla, every day offers products originating from the Villa, such as quesillo, cheese, yellow bread, as well as Oaxacan products, mainly regional foods and snacks such as molotes, quesadillas, empanadas, memelitas, tlayudas and tostadas. Inside the Porfirio Díaz market, there are also businesses that offer flowers, toys, clothing and handicrafts, meat and seafood, nieves, among other items.

Tianguis (from Nahuatl tiyānquiztli, 'market') is the traditional market that has existed in Mesoamerica since pre-Hispanic times and has evolved in form and social context over the centuries. The heritage of the tianguis is a mixture of the mercantile traditions of the pre-Hispanic peoples of Mesoamerica, including the Aztec, and of the bazaars of the Middle East that arrived in America via Spain. The tianguis are characterized by being located semi-permanently in the streets and on days designated by uses and customs, these vary in each population, in which the local community acquires various products, from food and clothing.
