I bought a latte at the Santa Monica library coffee shop a few weeks ago and it came with an advertising sleeve and a free sample of Orbit Gum.

New cars come with a free trial of XM Radio

and this box of Special K has an offer for free Nail Polish.

Why ask why.

The point is that people like free stuff and if you want to increase sales of your product give it away. In whatever avenue is available.  Free matches are gone.  Free pens are still here.  But what about free kleenex, free fans or free business cards with a quote on one side and a free offer on the other.
