Input: Buyer: I'm afraid I can't see the picture of the item
Seller: Yea, apparently there's an issue with the upload. But if you google it, you can see a photo of it and the $2300 original price tag when brand new.
Buyer: what color is it? 1500 is a bit steep for me right now...
Seller: It's black. Yea I know $1500 is a bit steep for a bike, but this thing is made from space age alloys. I'm already taking a huge hit on it considering I'm knocking off $800 off of the original price because I've ridden it a couple times.
Buyer: Understood. It is pretty impressive and that's quite a discount. What do you think about $1,000 and I come by to help narrow your butt?
Seller: If my butt was narrow, I wouldn't need to get rid of it. $1000 is way too low. Can do you $1300?
Buyer: I can do 1200. I figured you could use the narrow butt for something else since hunching would still be a n issue for you. A narrow butt is good for many things. Versatile.
Seller: $1250 and you can have the bike.
Buyer: Okay, but can I get help with my posture as well? I hate the way I hunch.

Seller:

Output:
bike
