The 260 million dollar figure isn't for store visitors, it's for stores + websites. From walmart.com:

> Today, nearly 260 million customers visit our more than 11,500 stores under 63 banners in 28 countries and e-commerce sites in 11 countries each week.

> According to statisticbrain[2], Wal-Mart stores (location not specified) have 100 million customers (not visits) per week.

The source you cited looks like the location they're referring to is worldwide. They cite "Total Wal-mart sales annually" and that lines up with their total global revenue, so I think it's a fair assumption that their "Total numbers of customer per week" would likewise be globally.
