Hey so I'm interested in the Tile mate tracker, could you tell me more about it? 
Absolutely! The tile tracker works over bluetooth to help you keep track of items. For instance, if you lose your keys often, attach the tile tracker to them and you can find them with your Bluetooth-enabled device.
So I'm interested. How long have you had it for? Why is it so expensive?
I got the item this past Christmas, but I just never used it. It retails for over $25, so this a discount for a new product!
Can you drop it off and I'll give you $10 for it?
I can drop it off, but I really can't go lower than about $15
If we can do $14 it's a deal.
Alright! It's a deal.
