Report says Amazon to expand its store-brand offerings

The new products could include nuts and spices and other consumer goods such as diapers and laundry detergent.

According to the WSJ article, the new private-label goods will only be available to Prime members as well.

In addition to delivery services such as Fresh Direct and Instacart, Wal-Mart Stores Inc. last month said it's expanding its service that allows customers to order groceries online and then pick them up in the parking lot of their local store.
