Carded
My great student card heist: I live in South Australia. Basically, the cost to apply for a uni degree here is about $60. So you apply for a degree, enroll in topics, get your “full-time student” ID card, then unenroll in all your topics. If you unenroll before the census date (which is usually a month or so after uni starts), you don’t get charged for the course…but they don’t ask for your student card back!
That means that you get to claim all the sweet sweet student discounts. The best part? Awesome discounts on public transport. If, like me, you get public transport twice a day, five days a week, it costs you almost $40. Having a student card halves the cost. So you basically make up for the $60 you paid to apply for uni in three weeks of catching the train.
