Buyer: Hi there! I am interested in this bike but your listing already says don't be one of those idiots and send me a low ball offer. So is there room for negotiation here?
Seller: Well, there's always an opportunity to negotiate.
Buyer: Great. So have you used the bike for a long time?
Seller: Yes, I've had it for 2 years.
Buyer: Is the condition good? I mean, any scratches or scraps?
Seller: Well, I never rode it, it's a back up bike, so it's in good shape.
Buyer: Great. So would you accept $1840 for it?
Seller: I don't know if I could accept $1840, as I said in my listing it's worth every penny and much more.
Buyer: So what's the last you can go?
Seller: If you're willing to come by and pick it up, I'd let it go for $1900.
Buyer: Sure I can do that. Its absolutely not an issue for me! I would definitely accept this offer
Seller: Okay, great. I'll have the bike ready.
Buyer: Thanks
Buyer:
Seller:
