Amazon Prime members get free two-day shipping, and they get Amazon Prime Instant Video, which is like Netflix except it comes with the additional benefit of getting free two-day shipping on anything. Normally, it costs something like $80 a year, but it's free for one year if you're a college student.
After you sign up, use the "Shop Amazon" link on the front page before buying stuff from Amazon. That way you help YWS out at no cost whatsoever
Also, Amazon Prime is incredibly helpful. I've had it for a couple years now, and the free two-day shipping makes it almost always more convenient for me to shop on Amazon than to go to a normal store.
Amazon also has textbooks for much cheaper than your campus bookstore.
Am I shamelessly plugging the Amazon links on the front page? Yes. Do I care? No!
