Negotiation books/courses

Anyone have good books/courses on negotiation they can recommend.

Is there a specific area that you are most interested in? (wholesaling, short sales, sub 2, etc?)

Hi Mdhaas:
Thanks for your reply. Wholesale and Lease Options.

‘Secrets Of A Master Negotiator’ By Roger Dawson. Best book out on negotiating. Roger’s backround has been negotiations on behalf of countries fighting etc. Great books.
