Lulu is offering free "Published by Lulu" service
Lulu.com. Free "Published By Lulu" service for a "limited time." This service gets your book distributed to online bookstores (and theoretically bricks-and-mortars bookstores). Lulu is the publisher on record. Ain't business competition wonderful? :)

It gets you to their websites, which is great and very worthwhile. but I am not sure it gets you even theoretically into real stores except if someone decides to proactively special order it--due to non-returnability.

That's why I said "theoretically." :)
