Thanks for the reply. Yes, I did buy it from the Sony store. I haven't tried, but assumed it had DRM.
I had a feeling it was something with how they made the book & there was not much I could do. Why they would think margins like that are a good idea is beyond me.
This is just another example of how DRM only serves to hurt the honest people that actually pay for things. Piracy will always be there & we get screwed in the end.
