In the 19th century, the village still had three grocery stores.
At the end of the 1800s, Xavier Freyburger moved to Wentzwiller with his wife Eugénie Wanner. He came from Ballersdorf, and had a bad reputation as a schoolteacher. Therefore he preferred to focus on a grocery store, and opened his shop on Rue Principale. The store was closed in 1940 during the evacuation to Les Landes, and the building became a residential house.
On Rue Principal, the Wanner restaurant also housed a grocery store.
From 1920 until 1981, at 3 Rue du Presbytère, a third grocery store operated, which also served as a tobacco shop and a post office with a public telephone.
Until World War II, the residents of Wentzwiller could do their shopping at the Freyburger grocery store. It had two doors: one with a sign indicating the entrance to the grocery store and the other for the residential house. In 2022, the building was renovated and is now used as a residence. The grocery store was no longer essential as residents began to source their supplies from supermarkets.
