One of my followers, Alina, brought this deal up to my attention:
Buy a $100 Lowe's Gift Card (will only work on Lowes) at HEB and use 2 of the $15 off any $100 HEB Digital Coupon
and it will deduct $30 off your cart!
You will pay $70 on a $100 Lowe's Gift Card!
I am not sure why both are deducting for one gift card purchase but it's worth a try!
