Sam's Club is introducing changes, with reports varying on the number of changes, ranging from 4 to 6, that are expected to take place. Some of the changes are set to occur as early as next month, although the exact nature and scope of the changes are not consistently reported. Additionally, Sam's Club's parent company, Walmart, is also making changes, including a campaign and updates to its Great Value products, although it is unclear how these changes relate to those at Sam's Club.
