Hello
Hi, I'm interested in the smart watch you're selling
Great, do you have any questions?
How old is it?  Does it work properly?
It's brand new and works perfectly.
Cool, are you willing to come down on the price some?
Sure I could probably come down on the price for a reasonable offer. Especially if you are local and can pick it up so I can save on shipping fees.
Yes I can pick up, not a problem.  Would you take $100?
