HEB Grocery Stores - Buy $50 Home Depot GC (in store) and get a $10 HEB GC. Limit 1. Good deal if you need any Home Depot Gift Cards.
Tip: Set up multiple accounts if you need more than 1. You just need a phone to receive the welcome text if I remember right. I think i set up like 10 accounts a few years ago when they had Lowes GC's at 20% off. Cashier didn't bat an eye.
