I have bought many O'Reilly books from Amazon and I am satisfied with the purchases. Moreover, I have been Safari client for some months that I needed a big amount of IT information. I think the best point of buying O'Reilly products is its quality/price tradeoff.
I have seen that you have some interesting videos but from my point of view they are extremely overpriced: 10$/hour!!
¿have you been thinking about selling the videos at a more reasonable price?
