There are four different types of Walmart stores: Walmart, which is a general store selling mostly general items, no grocery. Walmart express which is the size of a dollar general and sells only grocery. Walmart Neighborhood Market which sells only grocery. Walmart supercenter which sells both grocery and general. Despite it's size, this is considered a supercenter because of what it sells.
I would assume because it has groceries. Sorry, I'm not a Wal-Mart fan or expert. Good luck with seeking the correct answer.
