At one point- not so long ago—Wal-Mart was putting up small convenience stores to catch the ‘bread & milk’ shopper between bigger trips to the grocery store.
Didn’t see any in N Nevada. I don’t know where they are, but I think they still exist.
THey shut down Walmart Express stores in 2016. THey are still trying tho - this time with Sam’s Club! https://www.forbes.com/sites/barbarathau/2018/06/19/after-its-own-mini-format-flopped-walmart-gives-small-stores-another-try-via-new-sams-club-concept/#1656bdd053c8
Those were the neighborhood stores. There was an article that compared Dollar General’s expansion strategy to Walmart’s dating back to Sam taking helicopter rides and looking for growth patterns. Walmart needs to emulate Dollar General or just buy it. They could use their logistics and buying power to lower costs and make the ex-Dollar General outlets more profitable. I think Walmart should look at well run convenience store chains like Wawa, Go-Mart and Sheetz as possible vehicles for market expansions. Imagine ordering from the Walmart website and picking up the item at your local Walmart owned convenience store.
