How much would these games sell for at a gamestop for cash not credit?

Using the Gamestop site's estimation of price and Amazon.com, I'd roughly say without the cash "penalty", it'd be around $100 ( I got $100.93). With the "penalty", given it really is what I think it is, I estimate it to be worth $80 (I was using an odd calculator, so rounded, the exact result was $80.74)
