Oooh, make her a mixtape! Buy songs that remind you of your relationship & purchase them on the Amazon Digital Music. Depending on what songs you choose--you could end up with enough $ left over to get a mix of things for her!

A cute bento box may also be nice choices. Especially if you whip her up a nice lunch to put in it! Take her on a picnic date! They also have molds for different types of food in the shape of cute animals.
