Since it's so close and across the country, I've gotten prices from $300 to $600.
Then, I saw priceline.com where you can enter your own price.
How does priceline work, exactly?
How does it let you get 400 dollar flights for whatever amount you put (I tried $50 to see what it would do)?
Is priceline a bad idea? It seems fishy to me.
Edit: What's the cheapest site you know of?
