When we were operating local Karaoke shows in bars around town, a travel agent gave us about a dozen "Free Trip" promotional packs to give away as prizes. It was a week's trip to Florida, everything included, all in a nice package. When I checked it out, it turned out to have "Fees" attached, which made it cost, oh, about what it would cost if you booked it yourself, in fairness maybe a tad less. We gave them all away, but never heard if anyone actually went on the trips. I guess it made folks happy to win something, even if it was in essence, nothing.
