One thing I noticed, looking further at their tips on negotiation, was the link to another area:
http://www.businessballs.com/sharond...cilitation.htm
I had a look at it (and at the main link) and although I liked the emphasis on having a sales 'reflective diary' which I think is really important in all types of business, I had a look at the tips and the type of questions they suggest you ask, and it looked very much like most of the (good) sales courses I know. It is really about asking the questions that will help the seller and the buyer realise how the change/purchase can be justified.
Or am I missing something?
