Hello CaraM,
Looking forward to receiving my own K3 soon... only just shipped now.
The pricing of eBooks is a big point of contention now with a lot of people. I agree that $9.99 is probably a bit over the top for most books. I think many people's 'sweet spot' is more around half of that or less. There's been some reports of eBooks being even closer to $20.00
Good luck with filling up your K3... I know it's going to be quite an interesting process here.
Paul.
