Give up the first money and walk out

It will be hard for you to sell later. You can not ask the first payment back, if I remember right , it is 1000USD right? Compare to how much you gonna lose when you sell it that is nothing.
They won't pay you back that but I think if you insist you can always walk out, come on! that is my money. I can even return a 1 dollar stuff back to walmart, right?
