I understand if I low balled someone, but I just do that to test the waters. But I would like to make a fair deal that works out for the buyer and seller. I’m constantly messaging the seller because I actually want to buy the gun. I just think it’s disingenuous to the buyer as I’m willing to make a fair deal for the both of us. As I have said, I have purchased a Glock through here without much issues.
Don’t feel too bad though. It was a beginner mistake. You could have done a lot worse by offering $1k or flaking on the seller on meet up day; that would have been an insult.

Do you happen to be new to the off roster ppt market via classifieds; any experience on calguns (not this site)?
Just know, those off roster pistols are not that hard to acquire since those are not considered exotic or weird pistols. They will pop back up again from a different seller. Wait, scroll around, and look for new ads. It might cost less, same price, or more. You might even see a different off roster pistol that you want instead of that one. For now, just see it as you saved the money that you could have spent on those.
I have been ignored twice before (back on calguns) even though I was willing to pay the listed price for ammo; with a decent positive itrader history. I asked if they were 03/coe friendly, where they honor the 03/coe exemption of doing cash and carry, without needing to go to ffl dealer to do the transfer fee, after I show them my credentials, cash payment, shake hands, and be on our way. Both never responded. I had to understand some people really don’t know about the exemption and might think it’s some kind of set up; this was by learning from other sellers who did not know about the exemption (or even what an 03ffl/coe is) and I needed to explain to them. Those deals proceeded, easy transaction for the both of us; positive feedbacks exchanged.
I’ve even been ignored once (calguns) for a good price on ammo after agreeing to pay listing price, was willing to meet that day, then something came up on the sellers behalf, so we couldn’t meet, texted back and forth, decided to meet a few days later. Few days later, I noticed my text messages were not being delivered; that meant I was blocked. I checked the ad and info was deleted; they were just testing the waters to see if they would get any bites. I realized that after noticing others who posted I’ll take it before me and after me were also ignored and were not able to buy it.
I’m glad you shared your learning lesson and reached out for others for their opinions and experience. I do think there was some humor/sarcasm to the irony in this situation. There was useful information in this thread; what we would call “free game”.
Another nice way to ask is; “does this price happen to be firm?”
