courtesy Filson A duffel bag is easier to stow than a suitcase. This one is by Filson. Luggage may seem like a great graduation gift, but for the kid going off to college it has real drawbacks. Any parent who has moved a teen into a tiny dorm room knows there is usually no place for suitcases. The better gift is a set of duffle bags that can be stuffed under a bed when not in use.
I agree completely with April's response! If you dont go with the money, there are tons of Graduation gifts out there. If you go to Hallmark, American Greetings or stores of that nature, you could find some really nice gifts. But if you go with money, those amounts April gave are appropriate.
