I dropped the price of my book "What the Hell is up with Heaven?" to FREE on Smashwords. I then made a request for help from readers to post the lower price to Amazon. A couple of days later, the UK price dropped to zero, but the US and DE prices stayed the same... kinda disappointing - I really wanted it free across the board. I did give away nearly 400 copies in a couple of days, so I was happy about that.
I'm still waiting on reviews to be posted - none have come in so far (bummer). On the positive and brighter side, I've had an uptick in sales on all my other books, including "Tear in Time", which the price was just recently raised to 2.99, so that really WAS a big boost to morale - whoohoo
Although the extra money was nice (it really wasn't that much extra - lol), I have to say, the biggest reward I received from it was the comments on forums by readers telling me that they loved the book. Dang, that was such a thrill. To me, that's what it's all about! It many it all worthwhile.
