FWIW informit.com has the same model. We have regular holiday sales (including a 4th of July sale starting tomorrow), update our eBooks, and offer the different DRM-Free formats including PDFs.
Informit.com is a Pearson owned site and sells the following tech imprints:
Addison-Wesley, Prentice Hall, Sams, Microsoft Press, Cisco Press, Pearston IT Certification, Big Nerd Ranch, Peachpit, Adobe Press, and New Riders.
And we currently have no plans to change that model-just make it better!
