Whoops! Here I thought it would take at least a couple of days for any submitted changes to take effect at all of the places that sell Boomerang, but Smashwords is quick as can be. So....Amazon and B&N (at least for now) are the places where you can still get it for $1.99. I have no idea how long it will take them to post the new price. But I do know the action on Amazon has taken a sudden turn for the, well, more active.
Get it while you can at $1.99, then tell all your friends, family and coworkers what a great book they too can have for just $4.99. You'll still be doing them a favor. And supporting the Arts. Which is a good thing.
