The drugstore chain said its new service, under its customer loyalty program that has more than 100 million members, will be in addition to at-home delivery and discounts on prescription drugs.

Earlier this week, Amazon.com Inc launched its online pharmacy for delivering prescription medication in the United States, intensifying competition for drug retailers such as Walgreens and CVS Health.

Walgreens also said its mobile app now features a broad range of health and wellness services, including a 24/7 pharmacy chat and booking medical care and vaccination appointments.

It also announced additional new benefits such as cash rewards for members of its loyalty program, myWalgreens.
