Query: Real lack of effort in publishing

To follow up on the printing. The copy I got was very, very bad. Pretty much every page has multiple printing errors making the book very difficult to read and in some places you need to understand the content already to make headway.The book used to ship with a CD. Now there's a sheet saying to go look at phptr.com for a download. I could not find the CD download, but I did find the book in pdf. At least the pdf can be read.Bad job Prentice Hall!
