In NZ, we provide stationery - given the list at the beginning of the year, and go get it. Some stuff is 'pooled' in the classrooms, such as tissues.
I liked it, because we could get the brands and quality we liked. We didn't find it inefficient at all. In fact, the stationery shop at the beginning of the year was something we enjoyed!
Textbooks were provided by the school - but they didn't have to be replaced very often because the curriculum doesn't get rejigged every five minutes.
Students who couldn't afford the lists could get help from the equivalent of Social Services, or from the school.
As in the UK, education in NZ has been consistently and seriously underfunded for a number of years. However, no school has had to cut its hours because it couldn't afford to stay open from 9-3 five days a week. (The school donation is also voluntary, and varies from school to school. Some schools put unreasonable and unlawful pressure on parents to pay).
In NZ, the right to a 'free' education, has sometimes been interpreted as meaning 'freely available to all', rather than being in cost to user being 'free'.
