This mixed-methods study explored SNAP users’ food and beverage purchasing patterns and perspectives regarding potential modifications to SNAP to inform the design of SNAP+, a healthy incentive program to increase fruit and vegetable (FV) and decrease sugar-sweetened beverage (SSB) purchases. Participants were recruited through a non-profit organizational network to participate in an online survey.

Most spend >$15 of SNAP (87.1 %) and >$15 of non-SNAP (60.8 %) dollars on FVs/month. Respondents spend
