Today from Buy.com is the Kingston 4GB USB Flashdrive - remember when these things were a fortune? Now only $7 plus shipping. Also, on the education train, check out these HD Travel Around the World BluRay disks for your wanderlust need or student's inquisitive mind.
Whatever you are looking for, I always advise Buy.com first, I have saved hundreds from laptops (the one I am typing on now) or even a great set of powertools. Enjoy!
