Connecticut’s Priceline is famous for its spokesman, William Shatner, who karate chops travel rates for savvy consumers. The site’s “Name Your Own Price” feature is for the flexible traveler. Here, you place a “bid” stating the price that you wish to pay for a ticket, a car rental, or hotel room. If your bid is accepted, you are bound to buy the ticket, even if, for example, the flight travels at an inconvenient time or includes a stopover. Those who want more control can choose specific flights and hotels at less amazing although still discounted rates. Book attraction tickets and even ground transportation here, too. Priceline operates in 90 countries and 32 languages.
