I bought a brand new furnace at a garage sale

I bought a brand new furnace at a garage sale. I was not expecting to find a furnace when I went out garage saling. I thought for sure that I would find something, even though I did not expect to find a furnace. I don’t even understand why the people were selling the furnace at their garage sale instead of selling it on the internet. I recognize prefer they could have gotten a lot more money for the furnace if they would have listed it on the internet instead of selling the furnace at their garage sale. I am absolutely super ecstatic that they sold me the furnace though. I asked them how much they wanted for the furnace, plus they basically told me that whatever I was willing to spend money they would take for it. I didn’t recognize how much a furnace was worth, so I asked them. They sold me the furnace for a hundred dollars. They told me that they had just bought the furnace a month before, plus it had never been used. They bought it from a store that was closing, so they got it for a pretty great deal. It turns out that it was the wrong furnace. I told them to list the furnace online to see if they could sell it there first, but they said that they didn’t want to go through the hassle to list the furnace on the internet. They sold me the furnace, plus I am so grateful because our old furnace had been giving me some trouble. Thankfully, our new furnace will work great for our house.
