I think there are some valuable lessons to be learned by this sale for O'Reilly, tech publishers and authors.
* 9.99 standard pricing will result in incredibly high sales volumes (the servers would not nearly have been overloaded if everyone wasn't clamoring to get their purchases in before the deadline)
* Publishers and authors need to decide whether they want larger margins w/low volumes - I am of the understanding that selling 5k copies is considered a best seller in the tech market - instead of lower margins with higher volumes. I'm hoping that the results of yesterday's sale might make them consider the first point above.
It would be interesting to see if O'Reilly released some statistics on book sales in the wake of yesterday's server bloodbath.
Myself, I bought a pile of books that I otherwise would not have bought. I have an O'Reilly Safari subscription that is already saving me tons of money, and the low price just pushed me over the edge to buy some local copies of books that I might have otherwise just had in my bookshelf for a month.
