"Nudge" Web-Based Supermarket	"Nudges" in Web-Based Supermarket	Participants will be asked to simulate one grocery shopping trip in a web-based supermarket and to select three unique beverages for their household that their child would drink. Participants randomized to the "nudge" web-based supermarket will view beverages in descending order of healthfulness (i.e., the healthiest beverages will appear at the top of the screen), view a store landing page promoting the healthiest beverages with a health message, and be offered healthier swaps for sugary drinks at point-of-selection (i.e., immediately after selecting an item to be added to their shopping cart).
