The AOD FCU visa offers 3% on any purchase (which would inherently include grocery). As a smaller credit union their application process is a bit stringent (they want proof of income in two recent paystubs, government photo ID, selfie holding up a piece of paper saying AOD FCU) and they're a bit conservative as a lender (smaller limits to start, CLI is treated reapplying, min. $5K limit), but then again, 3% CB everywhere.
