You couldn't go wrong with a new phone or a camera. Cell reception in Bancroft is really spotty, especially on the lower decks, so a signal booster would also be nice. If Sprint is your carrier, you can pretty much assume that you won't have much contact with your plebe
Other ideas...
-Ipad (It's small and portable. You can store it easily and do lots of unplebish things with it)
-Protein. Who likes king hall, anyway?
-Air fresheners
-Snack food
