So I see For Trade ads quite a bit, and I'm wondering what the psychology is behind it. On two occasions, I've wanted a machine that somebody was only looking to trade (I don't have enough machines to want to trade anything at this point). Both people stuck to their guns on the trade rather than selling to me outright.
Let's take two machines that are desirable and priced about the same: Shadow and Congo. (This is purely hypothetical, BTW.) If somebody wants to trade a Shadow for a Congo (or vice-versa), and they can't find somebody to do the trade rather quickly, why wouldn't the person just sell the Shadow outright and take the money to make an offer for somebody else's Congo? Or just do that from the outset rather than waiting forever for the right person to come along?
I'm not understanding why people are averse to selling and buying instead of just trading.
Can anyone enlighten me?
