The specific aims of this proposal are to 1) develop online food retail nudges to discourage sugary drink purchases and promote healthier substitutes; 2) examine the impact of online store nudges on purchases of sugary drinks in an online randomized controlled experiment with low-income parents, including Supplemental Nutrition Assistance Program (SNAP) and Women, Infants, and Children (WIC)-participating parents, of children age 1-5 years; and 3) disseminate findings to retailers, including those participating in the SNAP Online Purchasing Pilot.

• previously purchased fruit drinks for their children;
• have ever shopped for groceries online in the last 12 months,
