Hi is your thermostat still available
Yes it is
Great is there anything wrong with it?  How old is it?
It was only briefly used, so it's in perfect condition.
ok would you be willing to take $30 for it I can come get it right away.
I really don't want to go any less, it is perfect.  I will even download the manual for you.
well I can do that myself dont trouble yourself.  Could we maybe meet in the middle and do say 35
I just listed it, so I don't want to come down too much.  How about 37 and it's yours.
