Walmart will begin delivering prescriptions across the U.S. early next year, as the retailing giant strives to keep pace with rival Amazon in competing for health care dollars. Walmart's new service includes new prescriptions and refills, which customers can receive along with groceries and other products, the Bentonville, Arkansas-based company announced on Tuesday. Prescriptions will be delivered in as little as 30 minutes and should be available for over 86% of American households, according to Walmart.
