Wal-Mart has teamed up with MaPS, an independent market research firm in Boston, to administer this survey. Data is provided to Wal-Mart anonymously; if you choose to enter the sweepstakes, only MaPS will receive your personal contact information for the purpose of sweepstakes administration. If you would like to receive special communications from Wal-Mart, you will have an opportunity at the end of the survey to opt in. However, if you do not opt in, survey responses will never be linked to your personal contact information and will only be analyzed in aggregate. MaPS, Wal-Mart Stores, and Walmart.com will not sell or rent any of your personal information or responses to surveys to any outside third party. We will only use this information to enhance your shopping experience at our stores or on our website, and if you choose to opt in to receive communications from us you may receive marketing materials from us. Your information may be shared if we are legally required to do so.
