Albertsons & Vons is offering a coupon for $5 Off Your Grocery Purchase of $5 or More. It seems insane but I just clipped it online. You can go to Albertsons or Vons' website, login and click on the "Just for U" section. YMMV but you may see this coupon there, and you'll want to clip it. You can also do this via mobile app.
In my experience, not everyone will get the same coupons in the "Just for U" section, so YMMV. But obviously $5 off $5 is basically $5 of free groceries!!!
