no because you usually can not get what u should for something so you sell it for less.... i know i have sold things that were worth 30,000 for 15,000 just because i wanted them gone. Not because i needed the money. But if someone wanted to trade me a 30,000 motorcycle, im not going to give them my item and 15,000 more cash!!! But if they want to buy it out right 15k cash!
This is just my theory
