Can you Negotiate with a Wholesaler?

[Brian Pleshek]

I have always found my own properties.  Now that I'm starting to go after more, I might start to use these guys.  I fully understand that they're there to make a buck finding me a lead and I have no qualms with them making something off their work.  But if a wholesaler brings me a deal based on criteria that I have previously given him is it rude/unprofessional/just not done to try to bargin with them over the selling price?  I ask here so that I don't look like a fool later if it's pretty much a vote up or down rather than a negotiation.  So what is standard practice?  I don't want to offend the guy and never get a call again if I am in the wrong on that.  I'd rather look like a newbie here than in front of the guy who I might be doing business with for a long time.

Thanks,

Brian
