I personally need to learn how to negotiate. I almost never offer less than asking price, I just feel bad doing so - but now I see that it's almost expected.
It's funny though - I do expect it from buyers, but I don't expect it when I'm a buyer myself. Guess I need to change that mindset a wee bit.
Since I believe 100% in Grade A animals being worth more than their lower graded counterparts, I think that's why I rarely counter-offer when I'm a buyer, because I'm going after the Grade A animals.
