After going to three schools throughout my school career, I have realized that any given school has some system of supply and demand. My friend, for example, buys Beats earbuds in bulk on Amazon and sells them at a little lower than retail price in his school, making ~$30 each pair in profit. At my school now, it's websites. I have been experimenting in HTML after hearing these complaints, and I already have one buyer, and a three page unhosted website going for $30, all pure profit, and the website only took around 20 minutes to draft and ten more polishing, and the buyer loves it and will pay me tomorrow and take their code. I'm sure if you listen around your school and do a bit of research, you could be making a butt load of money very quickly, and that number will only increase due to rising demand.
