GiftCardMall is selling discounted Lowe’s gift cards. You can purchase a $100 gift card for only $90. These purchases often earn 6x fuel points also. But right now because of their 4x deal or maybe the weekend multiplier they are earning 12X instead. A great deal for fuel savings.
I’m not sure exactly what is causing them to earn 12 x but these purchases do not code as groceries so just use any credit card that earns at least 2X.
