Hi I just saw your post for a fitbit for sale
Yes.  I still have it.  Are you interested?
I might be, but the price is a little high for a used fit bit. I was thinking more around 20.
Hmm, I really do want to sell it, but I bought it for $85.  $20 would be way too low.  How about $50?
With all things there is depreciation, especially for exercise equipment, how about 25?
I went down $10 and you went up $5.  Let's make a deal and meet at $40.
Tell you what, with the 2 bands, I'll go to 35; what do you say?
Deal.
