In case you did not know, many websites and stores offer discounts to college students if you use a .edu email address (you have 2: netid@illinois.edu and netid@uiuc.edu) or show your student id. There are too many to list, but Amazon Prime is probably the best known (and quite useful). Another service that is useful for CS majors that offers a college discount is GitHub. GitHub has even put together an awesome pack of free software (https://education.github.com/pack) containing everything you need to turn your next project idea into reality without spending a dime. Also, local movie theaters give discounts if you show your id. In short, before you make any purchases, I would take the extra minute to search and see if you can get a discount.
