Have just asked my forces dh, who says it depends where she is and who she is with as to what is available.
He suggests books/magazines, mini perfumes or deoderents(non aerosol), dvd of photos/birthday messages,mini mp3 player with fave music or messages,nice sunglasses,fave tea bags (herbal or normal) biscuits etc.
He is still thinking but hope that is some help in the meantime
