Hello, are you interested in the bar stools I have for sale?
I certainly am. They are exactly what I have been looking for. 
That's great! Do you have any questions about them?
Are the seat covers removable?
yes they are! You can throw them in the washing machine and bam, back to new!
That is fabulous!!! Is the price you are asking firm or are you willing to negotiate is I offer to pick them up?
