I had pre-ordered Under the Dome at $9.00 several weeks back.
(Yes, I know... I wasn't going to get it either, but changed my mind.)
Looking at it again today, I noticed that the price was now $7.99 for the pre-order, so I canceled my original one and re-bought it.
I thought there may be others out there who would want to do the same.
Under the Dome for Kindle
Enjoy!
