All Packt ebooks are $5 13 years ago
I just bought Mastering Web Application Development with AngularJS which is also for sale on Amazon and has pretty decent reviews there: http://www.amazon.com/Mastering-Web-Application-Development-...
Turns out, you get a discount for print books if you own the e-book, I got 50% off after going back to the site once I bought the e-book: €17,50 instead of €34,99
So... €21,88 for both instead of €34,99 (you always get the e-book free if you buy the print version it seems).
