Do buyer's real estate agents try to get you the lowest price?

[Tom Smith]

Do buyer's real estate agents try to get you the lowest price possible, or do they usually not bother to negotiate? What is the incentive for them to get you the lowest price on a home you are trying to buy? When you are buying a property, can you tell them what price you want to try to negotiate for? Do buyer's real estate agents always haggle for you or do most not bother? I assume it depends on the agent's ethics and whether the agent is serving your best interest.
