Chile
In Chile most services and businesses are closed on both New Year's Day (January 1) and Labor Day (May 1). Much like on the U.S., alcoholic beverages in Chile are not sold on Sunday mornings, while on election days their sale is prohibited by law during the entire day (starting the Saturday before).
Late in 2010, some Congressmen (after the four-day Bicentennial holiday was proved successful) asked for a law that would forbid the opening of supermarkets and department stores on Sundays, however retailers claimed that Sunday shopping made about 20% of their weekly sales, more than other day of the week, thus preventing the law from taking place.
