As of May 2015, Amazon.com and Walmart.com sell Mrs. Grass soup mixes. Walmart also offers them at certain brick and mortar locations. In addition, both Albertsons and ShopRite grocery stores carry the soups.
Amazon.com has a few varieties of Mrs. Grass soup available, including chicken noodle, onion and beef vegetable. Both individual and multiple packages are sold. Walmart advertises large-count packs of the Mrs. Grass soups online, but customers purchase two-count boxes only at local stores.
Mrs. Grass products, sold under Wyler's label, include both hearty and noodle soup varieties. Multipurpose mixes are also useful in dips and as recipe ingredients.
