A variety of local grocery delivery services are online, including Peapod.com, Instacart.com and WeGoShop.com, as of 2015. Many smaller companies may be limited in reach and delivery area, while companies like Amazon and Costco are able to deliver most basic grocery items anywhere in the United States.
Online delivery services like Instacart.com or WeGoShop.com allow customers to choose from a selection of local stores. Representatives receive shopping lists from a customer, fill the order and deliver the groceries directly to the customer's home, often on the same day. Larger companies like Amazon or Costco fulfill orders online, but orders may take longer to arrive.
