Bargaining

So I wanted to buy a flash memory reader for my computer so that I
could pull pictures off my camera memory card quickly. I went to the
electronics district with a friend. Of course at the first stall I
was quoted a high price. So I got a price from them and said I'll
think about it and look around. So the next place I told them the
price I already had and they gave me lower. I said I would think
about it. At the next place I found a better reader for a slightly
higher price. So I continued on, at each stall receiving a lower
price and telling them that I would think about it and look around.
They always laugh when you tell them what the other guy will give it
to you for and when you say you will go look around some more.
Hopefully they are laughing because they realize you are trying to
get the best deal. So in the end I got one reader for 45 kuai (<$6).
The initial price was either 100 or 80 kuai but was reduced to 60
kuai when I fibbed and told him I could get a different model for 50.
So I felt successful. And the device works well.
