I just found out that Humble Bundle has a book bundle for Terry Pratchett’s Discworld. A 39 book bundle that is redeemed through Kobo.com.
Edit: Only available in the US.

Same but I still prefer eBook/PDF quite a lot. I like it for my text books so I can easily make copies and not carry as much. But paper feels more at home for fun reading.
