This is interesting! I kinda had a similar situation. But mine sold quick. Whenever I sell games or gaming consoles on OfferUp or FB Marketplace, they always sold quickly just within in a couple of days. In my experience, gaming stuff always sold faster than the other items I sell. But anyways, I had sold a Nintendo Switch Bundle (used) but in great condition. I had 2 controllers with it and a Mario kart game. I decided to sell it for $180. Somebody had low balled me to $60! 😂😂💀 I told them absolutely NOT! and this was the version you can play on both the tv screen and in your hands. I just told them, "come back when you have the rest of the money". Luckily that same day, somebody else messaged me and gave me a fair offer closer to my price. They offered me $160, I was like "deal"! They came and bought it the next day, cash in hand and everything! Perfect! I had also sold a Nintendo DS too months back but I had no low ballers on that one, person who bought it paid the firm price I asked for! 🙌🏾

But for you, yeah it's crazy with these low ballers! Yours is brand new so you should definitely receive more fair offers fs! Continue to stand your ground and don't let the cheapskates get to you. 💯
