R.P.
Walgreens has holiday mugs that are marked 2/$1.00. What about combining some of the ideas posted already? You could use the mugs from Walgreens, put packets of tea/coffee in each, a chocolate covered spoon and/or honey stick, a biscotti or a home baked sweet treat in each, and then put a personal note like "have a break on me" (as suggested by another poster). It combines your budget and your creativity and still satisfies the "little something" for each person.
