It's been said before, but I'll say it again...

I have found.....and this is just my opinion, that the individuals who usually make an offer like the ones that are being described are not serious buyers....and you usually end up not selling to that person. In my experiences, you can tell by what the person is asking and how they are asking you is usually a good indication if you have a serious buyer. When I get short or curt question...I will answer them in the same manner...if they don't have the time...neither do I. Move on to a more interested buyer who will appreciate your product

I think the rude and simple reply to an add is usually a fishing expedition and they probably have been turned down so many times for the lowball offer that they dont bother with small talk.

I've had some great interactions, but one thing to note is that any piece that's a really good price goes within a few minutes of it being posted. I've seriously lost out of products that have only been posted for 6 minutes. So, often on my initial email I'll simply give a short and sweet " I'll take it, let me know your paypal address" Hardly rude, but I don't want perfection to stand in the way of getting a great deal on a piece that I've been looking for...

Kind of a mixed bag for me over the years, some great transactions some rough. On the buying side some of the nicer sellers were the ones who over rated condition or 'forgot' to mention that a product was modded or scratched. So who knows.

One thing I have found is that the definition of 'lowball' varies a lot. I had a couple things I asked about where the ad mentioned taking offers only to piss the guy off I think. To me 25% under asking price is about the lowball line, and my offer were maybe 20% down. Dosen't seem hard to reply "$xxx is my limit" or "let me see what else I get".

Not my experience, thankfully. Nearly everyone has been great and I've formed some nice connections with buyers and sellers over the years.
