I don't know if you read Scalzi or not. He posts a behavior-based analysis here (http://whatever.scalzi.com/2010/02/01/all-the-many-ways-amazon-so-very-failed-the-weekend/), with further ummm, pithy exposition here (http://whatever.scalzi.com/2010/02/01/seriously-now-theyre-just-being-dicks/). In short, regardless of whether Macmillan is being an idiot with their pricing model (ostensibly to do right by the authors, editors, and other members of the publishing industry - and having had this explained in person to me by Mary Robinette Kowal at Orycon last, I'm a lot more willing to give Macmillan the benefit of the doubt), Amazon is violating Wheaton's Law (http://en.wikipedia.org/wiki/Wikipedia_talk:Don%27t_be_a_dick).

This is not unusual behavior for Amazon; I'll spare you the gory details.

I second the suggestion of a previous poster. Use the GC's to buy third-party. That way AMZN only gets commission and not wholesale revenue.

And definite agreement on Baen; if any house is worthy of our dollars simply by house, they are, and they host some damn fine authors as well.
