As earlier reported, the move will allow Amazon customers to shop for toothpaste, lipstick and other health and beauty products through the online retailer's site. It also marks the first time that Amazon has given permanent space to a "third party."
The Drugstore.com tab will appear alongside tabs for Amazon's books, music, toys and other stores. Consumers will be able to use the tab to access Drugstore.com and to buy products from it. The company's store will continue to be accessible through its own domain name.
Initially, shoppers will not be able to use the same shopping basket at Drugstore.com that they use in other Amazon stores. And Drugstore.com and Amazon will separately ship items ordered through their various stores.
Amazon has signed a similar merchandising deal with Living.com. The giant online retailer owns stakes in both companies.
