Six-week study (Nov 4 – Dec 18): use a new, unreleased online shopping product on your personal phone and computer as part of your normal shopping, and answer three 5-minute surveys. Usage data is collected with your consent. You are compensated with a $150 Virtual Visa for completing the full study ($25 per survey if you stop early), paid by the company running the study (not by User Interviews). Optional paid interviews ($75).
