 What are Your Choices? You have choices about the various ways we collect, use, and share your personal information. We may send you marketing communications. You can tell us your marketing preferences by visiting our Communication Preferences Alerts page. We also personalize your experience on our sites and mobile services by showing you advertisements from Walmart or our advertising partners that are tailored to your interests. Learn more about interest-based advertising, including how to opt out. Some of our mobile services use your device's location information. You can adjust the settings of your mobile device at any time to control whether your device communicates this location information. We may also offer additional controls on our use of your mobile location information.
