With tuition prices skyrocketing I'm sure all of us are trying to find ways to save some money while away at school. Not that I'm an expert or anything, but I've found a few ways to save money while at school that I'll share.
Not that all of these things apply specifically to college life - most can be applied to "normal" life so may be worth reading.
If you've something to contribute, please post a reply and I'll add it to the list. This is more of a work in progress as I find new ways to save money at odd intervals.
Step 1: Transportation
Not like you won't being doing enough of this between classes, but walking to other places is a great way to save money. Gas is hovering around $3.80 a gallon as I write this whereas walking only costs as much as the food you run on. If you live in a city where everything is fairly close together, you can most likely get away with walking for 95% of your travel.
Most (if not all) forms of mass transit within cities (buses, subways, etc.) give student discounts. If you use mass transit frequently enough, buy a monthly pass. There might even be a bus or train that runs between your school and your hometown. I can take the Coach bus home from college for $1.25 one way (about a 40 mile drive).
You can also buy a bicycle (or salvage one, if you're savvy enough). Costs for that are only maintenance-related and I don't know a university that doesn't have a bike rack outside every campus building.
If you have to use a motorized vehicle, try to limit it to something small like a moped or a motorcycle. Not only do they get great mileage but most colleges offer discounted (or free!) parking for such vehicles. If you have to use a car, try to carpool. And, if possible, drive a car that gets good mileage (I know, if you're as broke as me you probably can't afford one!)
