They say that there's no such thing as a free lunch. No matter what, someone has got to pick up the tab. However, sometimes a company or business decides to be a little generous with a promotional campaign and pay the costs to distribute samples or portions of their goods and services to the public at no cost to us consumers. Although such free samples are usually small, very minor things of cheap value to keep costs down for the party providing it, a free sample is still a tiny perk for the person receiving it and is always graciously accepted... or, at least, that's what the companies responsible for the campaigns would prefer, but that's usually not the case.
