Priceline, on line with travel sites, some even let you name your price if you have enough time before you need the car. Hotwire just sent me a deal they had in Reno for $13.95 I paid $29 using them only last month in Reno[they were cheapest when I res.] so if you have time you can still find deals. Triple AAA or ARRP cards also help if you have.
