Nah. Before they were allowed only for like school clubs and things like that, but now they just literally take any box they see O_O NOBODY is selling anymore (before like 1 in 5 people sold at my school lol) so yeah it is pretty obvious if you are the only person selling now.You bought a iBook G3! Using money? I'm assuming you done that 3 years ago, right?
And to everyone who said that people dont sell stuff in their schools because stuff gets confiscated (too lazy to quote) then the smae in my school but people obviously dont care so much, and if its not open it wont get taken genrally. There is a boy in my school who is like a shop, who brings 10 Fantas, Vimtos, Galaxys, Snickers etc. every day!
