PacktPubPacktPub has been adding Delphi programming books and videos lately, and they have a big sale going on right now with them all available for just $5 each. I've not read or reviewed all of these, but I know most of the authors, and many are MVPs. 

Delphi Cookbook - Third Edition by Daniele Spinetti, Daniele Teti    

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.
