Grocery delivery is a service that allows customers to order food and household items online and have them delivered directly to their homes. This service can be accessed through various platforms, including websites and mobile apps, where users can browse products, add them to their cart, and choose a delivery time. Many grocery stores and delivery services, such as Instacart and Amazon Fresh, offer this convenience. Customers can select from a wide range of items, including fresh produce, dairy, and pantry staples, making it easier to manage their shopping needs without visiting a physical store.
