Seller: Hey there, you're interested in this seatpost?
Buyer: Hi can you please tell me more about the On One Pompino Frame-Easton Fork-Chris King-VO Grand Cru seatpost?
Seller: Yeah definitely, it's pretty new, the original selling price is 350 and we're only looking to sell it because we're moving. What's your budget?
Buyer: My budget is $260. I cannot really spend more than that because the wife will kill me. If you're willing to accept, I could come pick it up? I know gas is expensive right now so I'd be willing to make the trip to you.
Seller: Definitely, 260 sounds like a good deal, when will you be available to pick it up?
Buyer: I meant my budget is $182, I'm sorry! I was looking at your price and got confused. All I can afford is $182
Seller: Give me 200 and I'll drop it off, deal?
Buyer: Deal
