[quote name='Keenan Sandwich']When and how do we find out if we win? Do we get an email or something like that?[/quote]
I was thinking the same thing.
5. HOW ARE SWEEPSTAKES WINNERS SELECTED AND NOTIFIED?
On or around the close of the Entry Period, we, or a company acting under our authorization, will select one thousand two-hundred and fifty (1,250) Grand Prize Winners in a random drawing from all eligible entries received.
If you are a potential winner, we will notify you by sending a message to the e-mail address, the phone number, or mailing address (if any) associated with your Xbox LIVE account, or the mailing address listed on your alternate entry within seven (7) days following the random drawing. If the notification that we send is returned as undeliverable, or you are otherwise unreachable for any reason, we may award the prize to an alternate randomly selected winner.
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 e-mail address used to enter the Sweepstakes, or the person residing at the mailing address listed on your mail-in entry.
If you are a potential winner, we may require you to sign an affidavit of eligibility, liability/publicity release and W-9 tax form. If you are a potential winner and you are 18 years or older, but are considered a minor in your place of legal residence, we may require your parent or legal guardian to sign all required forms on your behalf. If you do not complete the required forms as instructed and/or return the required forms within the time period listed on the winner notification message, we may disqualify you and select an alternate winner.
