I don’t know how long they will offer this special pricing. O’Reilly Media recently switched to a subscription-only program. Packt is offering one too now, and I imagine this sale might be part of moving to only offer that subscription. I like “owning” media but also appreciate an “all you can eat” subscription, so I personally have a combination of both.
