How Did Your Sales Look Like During Launch Week?

The Kindle is for $7.99 and the paperback is like $17.99. Have you changed the price over time? Like meaning at launch, did you have a different price point than it is now and how did that look like? Yes, the original launch on the Kindle, I was advised to lower the book to $0.99. And my book actually couldn't be $0. 99 because of all the graphics inside. It had to be $1.99. The audiobook is pretty much completely controlled by Amazon for those who don't know.
