Brent's deal of the day

Yesterday Brent went with a buddy to Wal-Mart. His friend asked him if he was planning on buying anything, or just there to look around. Brent said, "No, I'm saving my money for [random stuff]… unless there is a ridiculous sale for today only where God of War is marked down from $50 to $20". Well, guess what they saw as they walked into the electronics section? Brent asked the cashier - "is that a ridiculous sale only for today?" and promptly bought it.

How does he do that?
