Explanation: sunk costs

What Is a Sunk Cost?

A sunk cost is a money that we have already paid to someone or somewhere and it can not be refunded. If you have already paid for something and your money can't be returned even if you don't take what you paid for , it would be hard to just walk away and let your money sink just like that. For this reason you may find yourself going against all odds to ensure that you didn't just give away your money for no reason at all.
