Industry sources indicate that Walmart is close to deploying a service paralleling Amazon Prime. Testing of Walmart+ will commence this month and will be an extension of Walmart Delivery Unlimited. This program involves an annual $98 fee for no-cost orders of $30 or more. This option is available through 1,600 Walmart stores. It is understood that the Walmart+ service will include placing orders using text messaging and will include discounts on pharmacy and fuel purchases.
