Negotiation & bargaining.

Negotiation is differ than bargaining - I think.
I prefer the purpose of negotiation is to overcome the "main objective" - as to bargain is only to reduce other's share in increasing our own shares.

Therefore in negotiation, the element of understanding other's concern & problems is essential which competency & sincerity is important.

Recently I've annoyed with the people who are simply just a strong bargainer - they just squezze us to the last cent even where we have been giving all we can to support them. I've don't mind to spend the last penny as long as it serve the purpose otherwise it is only about "greedy" !
