But several of you say you'll block someone who you feel lowballs you. What if, to them, it's a perfectly valid offer? Like my case. I see something I like, it's only being sold by one person right now. So I look at what comparable items have gone for in the last 6 months or year. If it's half what they're asking, I'll probably offer what others have gone for. Is that a lowball offer? If you really think your thing is worth what you're asking, you might think so. If I really needed it and yours is the only one around, supply and demand says, I'll pay what you want. But if it's a luxury item I don't need and I don't mind waiting to see if another comes along at what has been the normal going rate for the last year, I'll see if you'll take what I consider market value, and, if not, move on. The trick is having the patience to wait out the market when supply is uneven, I guess.
