Online grocery services allow customers to shop for food and household items through websites or mobile apps. Users can browse a wide selection of products, add them to their virtual cart, and choose a delivery or pickup option. This service provides convenience, especially for those with busy schedules or limited access to physical stores. Many online grocery services partner with local supermarkets and farms to offer fresh produce, dairy, and pantry staples. Popular platforms include Instacart, Amazon Fresh, and Walmart Grocery. These services often feature user-friendly interfaces, making it easy to compare prices and find deals.
