Microsoft has some sweet prizes lined up for users with a Bing Cashback account, whether already created, or one that will be produced on the spot, provided that they sign up for the $10k in L.A. Bing cashback Sweepstakes. The Redmond company is essentially offering a trip to Los Angeles, along with no less than $10,000 in cash for Windows Live members with Bing Cashback accounts. Microsoft only requires that users already own a Bing Cashback account, or that they set on up prior to completing the form on BingCashbackSweeps.

“The Bing cashback contest is officially live and you can now win a chance to do L.A. in style—with $10,000 in your pocket, a Hollywood makeover, a round-trip flight, hotel and serious E! studio time with Ryan Seacrest! This could not have come at a better time…some fun in the sun is just what the doctor ordered,” revealed Kristin Meldahl – Bing.

The grand prize consists of 4-day/3-night trip for two persons to Los Angeles, in addition to the $10,000 in cash. The winner will be able to enjoy hotel accommodations at Mondrian LA, and will even be able to get close and personal with Ryan Seacrest at his radio show and an E! News television filming. But there are additional prizes, albeit, less impressive. Users can also win a FIRST PRIZE consisting of $1,000 eBay Gift Card, and a SECOND PRIZE - $500 eBay Gift Card.

Microsoft has already kick-started the Sweepstakes on November 9, 2009, and users have until November 25, 2009 to enter. Winners will be selected on November 30th. “If you are a potential winner, we will notify you by e-mail using the Bing cashback e-mail address provided on your winning entry. If the prize/prize notification that we send is returned as undeliverable, or you are otherwise unreachable for any reason, or your eligibility cannot be verified, we may award the prize to an alternate randomly selected winner,” Microsoft noted. “If there is a dispute as to who is the potential winner, we will consider the potential winner to be the authorized account holder of the Bing cashback e-mail address used to enter the Sweepstakes.”
