Books that are released show up on Bookcrossing and such so let's say I am in South Carolina and see a title released in Washington. Not likely I will get to it, but the title intrigues me so I end up buying one somewhere. Or, maybe I am in the area but didn't find the book...I might still go buy it, disappointed that I didn't catch it.
Giving away books is never a bad thing: it gets your titles and name known and out there, and it promotes good public relations! Make sure you sign your books before hand and even slip in a web addy or business card. Sure, the book catcher has THIS title of yours, but you have 6 others for sale that they want to buy! :-)
Gotta love free or cheap promotional ventures!
