Most Shops In Montenegro Are Closed On Sundays
A simple but important tip for unwary tourists: nearly every shop in Montenegro is closed on Sundays. Grocery stores, cellphone stores, corner stores, malls, and some (but not all) pharmacies fall within this category. The majority of banks are closed for the whole weekend. On the weekends, they relax and spend time with their families. This is also one of the things about Montenegro you should know.
Since the country's Internal Trade Act took effect in October 2019, this has been the norm. Retail trade is likewise prohibited on public holidays (there are 14 national holidays in Montenegro).
If you're visiting Montenegro for the weekend or a holiday, make sure to plan ahead and stock up on snacks the night before!
