Limit: Each participant may enter one (1) time into each of the Daily Sweepstakes, and one (1) time into the Grand Prize Sweepstakes. Participants shall not be given more than one (1) entry into the Grand Prize Sweepstakes, regardless of the number of Daily Sweepstakes entered or entry forms submitted.

Any attempt by any participant to obtain more than the stated number of entries by using multiple/different email addresses, identities, registrations and logins, or any other methods will void that participant's entries and that participant may be disqualified. Use of any automated system to participate is prohibited and will result in disqualification. Sponsor is not responsible for lost, late, incomplete, invalid, unintelligible or misdirected registrations, which will be disqualified. In the event of a dispute as to any registration, the authorized account holder of the email address used to register will be deemed to be the Participant. The "authorized account holder" is the natural person assigned an email address by an Internet access provider, online service provider or other organization responsible for assigning email addresses for the domain associated with the submitted address. Potential Winners may be required to show proof of being the authorized account holder.
5. Grand Prize Sweepstakes: Sponsor will randomly select two (2) potential Grand Prize Sweepstakes Winners from all eligible Grand Prize Sweepstakes entries on or around October 31, 2007. Odds of winning the Grand Prize Sweepstakes depend upon the number of entries.
