One of my favorite budget buys that I've seen is this cute nail file set. I think I might have mnetioned them as well last year or the year before.
For 2.49 you get a trio of themed nail files, the perfect stocking stuffer or little gift. Pretty much every girl can use an extra file or two , all the more fun when they have snowflakes or owls . I pick up ones like these whenever I see them.
