Sometimes when you go on vacation, you want to spoil yourself and stay in a hotel that’s a little bit out of your price range. Or, you want to get a good deal on a rental car or flight but don’t have the time to check every car company or airline website to compare prices.

That’s where Priceline.com comes in. Priceline allows you to book flights, hotel rooms, car rental and attractions, all in the one place. Priceline is great when you can be flexible about dates, destinations and hotels, because that flexibility will help you widen your search and find the best deals. Keep in mind, however, that once you’ve made a reservation through Priceline.com, you cannot refund your booking under any circumstances.

Priceline.com is particularly handy for when you need to book a hotel. You can book hotels at the price listed by Priceline, or you can make a bid, enter in your credit card details, and wait for an answer. Bidding is great because you can find yourself scoring great deals – provided no one bids higher than you. You may find yourself staying in 5-star luxury for the price of a 3-star motel.
