Here are some ideas:
1. Quarters! I was forever running out of quarters for laundry.
2. A "gift set" of condiments - mustard, ketchup, salt and pepper shakers, sugar (or sugar substitute), hot sauce, etc. The delivery people always forget something!
3. Febreeze and Downy wrinkle releaser. 'Cuz you never quite get on top of laundry.
4. Shower tote, flip flops (nasty shower floors), cute towel set.
5. Thumb drive(s) to back up or carry data/papers/etc.
6. ID wallet thingy with key ring. The ones that my school sold were flimsy plastic. There are cute fabric ones that are more durable. I loved the ones that had a lanyard, because I was always dropping them.
Look at this (has zipper and silver key ring):

Or ID/phone holder wristlet

7. Small coffee maker (and a pound of coffee!).
8. Mini tool kit.
9. Throw blanket for chilly dorm rooms (you can even make those fleece tie-blankets for less than $10).
10. Small fan for sweltering days, white noise, or when the dorm's thermostat is set to 75.
If I think of others, I'll let you know.
