Amazon Prime

Walmart's grocery business is increasingly being positioned as the retailer's answer to Amazon Prime, according to a new report. By building loyalty through everyday food shopping, Walmart appears to be turning its largest category into the foundation of a membership-style ecosystem that can compete with Amazon's subscription model for customer retention and spending.

Amazon has issued what is being described as a warning shot directed at its Prime membership base, according to a report by TheStreet. The report suggests the retail giant is signaling a change or tougher stance affecting Prime members, though the exact details of the measure remain unspecified in the headline. The news is drawing attention from shoppers and retail watchers tracking how Amazon treats its subscription customers.
