Yep, I watched "The year of the flood go down" and bought it at approx $12.50 and then it went down to 9.99. I watched John Irving "Last Night in Twisted River" go down to 12.50 and then go back up to the same price as the hardback.
I didn't get it...
I still question that 9.99 is a "fair" price though, just as I question the same price for a MP3 Album. I'm not convinced that the cost of doing business is that high and I think the price is simply support the discount prices on the paper and CD (physical) versions...
