I once gave away mini gumball machines filled with M&Ms. My booth was pretty packed. The industry was almost entirely comprised of middle aged, middle class people with families, so they took them home for the kids (perhaps half empty). Personally, I always like a spare pen, but everyone gives them away, and I can't tell you the name of the company whose pen I last picked up.
