East Coast grocery chain Food Lion is offering a $10 coupon to use on your next visit when you purchase $100 in Visa, Mastercard or American Express gift cards through 5/12/15. There is a limit of one offer per transaction.
Based on the terms which can be found in their weekly ad, all Visa/MC/Amex gift cards should work including variable load cards. One reader has also confirmed a variable load Visa triggered the coupon.
A good use of this deal would be to buy variable load Visa gift cards with a credit card that has a grocery category bonus. Normally those cards cost $5.95, leaving a $4.05 profit plus any rewards earned.
