We've even done a project in the past (For Volunteer Appreciation Week) in which we created tags with neat expressions of appreciation and used double stick tape to attach it to the candy bars. We then loaded up a large basket with an assortment of candy and delivered them while doing volunteer rounds. They were very well received and the Volunteers (and employees) loved them. They were talking about it for weeks afterwards!
Really big bang for not a lot of money! I've attached some of the tags we used.
