With gas prices predicted to rise to as much as $2.50 per gallon in the U.S. there is a way to lower the pump price. Priceline.com announced last week it is launching a Priceline for Gasoline card whereby consumers will be able to name their own price for up to 50 gallons of gas per month. Starting May 20th, Priceline WebHouse Club, an affiliate of priceline.com, will offer the new service that is expected to save drivers 10 to 20 cents per gallon from most major oil companies. Over 100 national sponsors will contribute to Priceline WebHouse Club customers' gas purchases in return for customers' agreeing to try their products and services. The Priceline for Gasoline card is free to any consumer by accessing priceline.com. All four million previous priceline.com customers and all WebHouse Club members will automatically receive the blue colored gas card free in the mail. To bid, cardholders simply enter the ID number on the back of the priceline gas card and provide a major credit card or debit card account number. Cardholders then choose the grade of gas, the per-gallon price they want to pay, and the number of gallons desired (up to 50 gallons per household per month). If the bid is accepted, then priceline will charge the deal to the credit or debit card and notify the cardholder of the location of the local participating gas station. After each fill-up, Priceline WebHouse Club will automatically e-mail a receipt which also shows the number of prepaid gallons remaining. Priceline.com gas accounts may also be monitored online.
