Walmart Supercenter offers a wide selection of groceries, including organic produce, with competitive prices and a Freshness Guarantee. Customers can order fresh groceries online for free same-day delivery or pickup, with no mark-ups and the same low in-store prices. Walmart+ members enjoy unlimited free orders and free pickup, while SNAP EBT cards are accepted. The Walmart Grocery app allows customers to choose a pickup time, receive notifications when orders are ready, and have groceries brought directly to their cars, loaded by trained associates. Despite these convenient services, some customers find the pickup area busy and poorly designed, leading to near misses and safety concerns. The store in Mishawaka is noted for having a good stock of items and friendly staff compared to other local Walmarts. However, some shoppers mention long waits at self-checkout, occasional aisle blockages by staff, and employees who seem unenthusiastic. Overall, this Walmart is praised for cleanliness, professionalism, and a large selection, though the busy layout and staffing issues can affect the shopping experience.
