Good Afternoon!
Hello, I am interested in your UV bench lights. What kind of condition are they in.
These lights are in excellent condition.  They have been in our benches for under 1 year, but have not been used more than three times total.  
Awesome. Are you willing to come down on the price just a little?
As they are in relatively new condition, and new ones are selling for $500, I would like to keep close to my asking price.  However, if you are local and can pick up and would offer cash, I would be willing to negotiate a bit.
If I pick them up and pay you in cash would you sell them for $75?
How does $80 sound?
I can do that. Deal.
