Just came back from Microbrewcenter, where I was judiciously disbursing bits and pieces of my looooooooong dormant $1,931.00 gift card, a happy relic from my mad skillz fearless ferengi days (don't ask).
In the entrance alcove, they had a number of useful paperbacks on deep discount. I got:
Java In a Nutshell by David Flanagan (sku 648345) for $6.99
XML, The Complete Reference by Heather , 950 pages worth (sku 298828) for $5.99
Flash 5, Virtual Classroom by Doug Sahlin w/cd (sku059295) for $4.99
Dynamic HTML, The Definitive Reference (1,060+ pages) by Danny Goodwin (him, I've heard of) (sku 924340) for $4.99
They had others covering CGI, Chicken Humping (just making sure you're paying attention here) et. al. at similar deep discounts.
This was the St. David's Pa. store. The stores are not linked with their web site. My advice? Call.
Edit Oh! They had the paperback version of what might have been Upgrading and Repairing PC's, 14th edition (it was huge and similar in topic) for a commensurate price with the others. Are such books really of much use to you and I?
