I think iTunes featuring me this morning has helped my sales quite a bit. Seeing Spots is #42 in its iTunes category (which is about as high as it's gotten so far), and Isn't It Romantic? and All I Ever Wanted have climbed back up the contemporary charts and are at #23 and #35, respectively. I can't wait for Unwrapped to clear the Smashwords premium process and become available over there!
Meanwhile, In the Mood has gone free on Amazon UK (and is already #132 on their free list-- ETA: now it's at #112, yay), but not on Amazon.com... yet.
