Many of the computer 'bookshops' I know are all online, although many have a postal/telephone mail order facility as well. I would dearly like to get the book on shop shelves, and it is something we've been investigating for a few weeks now, the problem is that shelf space is limited and retail outlets have to be seriously convinced to stock a title on-shelf before making a purchase - often this involves serious negotiation. I have the same problem when I want to examine a book - I can't find it stocked anywhere locally! Otherwise, I know some places (I think Amazon.co.uk for one) offer a "try before you buy" scheme, and most (if not all) offer a refund if you don't want it and can send it back. I'll certainly look into it this week; in the meantime, if you haven't already seen them, you can of course dig through the TOC and a sample chapter which should demonstrate the style the book is written in:
