If you are enrolled in college this year and can provide a valid .edu email account, you can sign up (for free) for the program. The perks: exclusive savings on college essentials, and free two-day shipping for an entire year on textbooks and millions of other items (which is really handy when you get put in that class the last second and need the textbook like, yesterday, but don't want to pay an arm and a leg at the campus bookstore).
Just click here to sign up--it takes less than two minutes! I love it, and I love being that nerd that gets the textbooks ahead of time and pours over them. (Is anyone else like Hermione Granger in this?)
