I'm interested in the spider you have for sale. It seems too good to be true.
You are not dreaming, it is true. 
Would you take $2500 for it?
That's a little low, but I will take $2600 if you can pick it up this weekend. 
I will scrape together another $100 by Saturday and pick it up then.  It's a deal at $2600.
Yea Boy!
