Priceline - FREE Pricedrop Protection: Up to $600 cash back if prices drop after your purchase

William Shatner's alter ego, the Priceline Negotiator, has done it again! Check out this link for information on the Free Pricedrop Protection Program at Priceline. If you book a flight on Priceline and another Priceline customer books the same flight at a lower price, they'll refund you the difference - up to $300 cash back. The same applies to vacation packages, except you can qualify for up to $600 cash back. This offer will expire 06/01/2009, so be sure to start booking those trips now!
