Food Lion sells $500 Visa, Mastercard, and Amex gift cards, but as of the past couple years (at least) they didn’t allow payment via credit card.
The good news is that they’ve now began accepting credit cards again. There is a daily limit of $10,000 in purchases (including fees). Up to $2,000 can be purchased with a regular cashier and beyond that will need an override.
Lots of grocery stores who stopped taking card payments due to fraud are now reevaluating their position due to the enhanced security of chip cards, or other factors, and now allow credit cards on prepaid purchases.
