I have many textbooks available for sale including these two. Please email me if you are interested in any of these books:
I have the binder for the GM600, The Successful Business Plan (the deluxe binder edition; ISBN 978-0-9740801-0-9), that I ended up not using as I shared with my partner. I bought the binder for $90 plus shipping but willing to give it to a student for $80.
I also have the book for HR582, Understanding & Managing Diversity (the fourth edition; ISBN 0-13-206910-5I) which I bought for $96 plus shipping but willing to give it to a student for $85.
