There’s yet another deal on Lowe’s gift cards this one at GiftCardMall. You can get 10% off on both virtual and physical Lowe’s gift cards, which vary from $20 to $500.
GiftCardMall is listed on a few cashback portals that pay out 2% on third party gift cards. On top of that you can also earn at least 2% in credit card rewards and possibly 3X with the Citi AT&T Access More Credit Card.
