There are markets in several villages in the surrounding area of Baan Sammi. Their locations are within distances of about 5–8 km. Most of these markets are open daily from the morning to the evening. However, each market has a peak activity on a particular day with more stalls offering groceries and other things, and more farmers from around areas offering their agricultural products.
A briefly commented overview of such markets can be found here: https://docs.google.com/document/d/1D96_0s_1Qd35rPfM86NR1kk9FuR-bcuED-9gGJv-jmM/edit?usp=sharing
