For a limited time (probably very limited, as it’s capped at 50,000 uses), new customers can save $10 on any $35 Walmart.com order with promo code ELLEN10.
The code excludes photo, pharmacy, tires, gift cards, grocery pickup and delivery, personalized items and items sold by Marketplace sellers, but it seem that some gift card orders are going through, possibly just email delivery ones.
Email-delivered Nintendo eShop gift cards (or any gift cards, for that matter)? Red Dead Redemption 2? The NES and SNES Classic? They’re all eligible as long as your account hasn’t previously placed any Walmart.com orders.
