From my experience thus far, being a student equates to spending a lot of money on things you wouldn't normally buy. Books that never get used, access codes to attendance sites you use once or twice, and many more fun ways of watching your money fly out of your wallet. When it comes down to buying things you actually want to buy, there's usually not much money left in your budget. Here are some brands that offer discounts just for being a student #bless.
