Full disclosure, I work for Walmart in IT and specifically several components for the Online Grocery product.
Ask and ye shall receive. Buzzfeed's Tasty and Walmart have an integration that sounds like what you are looking for. Build a grocery list manually as well as from recipes in the Tasty app. Then when you "checkout" in the Tasty app it'll pre populate your grocery list in the Walmart app. You also select which Walmart you are shopping at so it shifts some of the items around to match like substitutes for what the recipe calls for.
