This Aug. 3, 2017 photo shows the Dollar General store, that took over the closed Walmart Express in Luther, Okla., Thursday, Aug. 3, 2017. Less than a year after opening its new concept stores known as Walmart Express, the retail giant shuttered the smaller stores intended to compete with dollar stores when they failed to gain traction nationwide. Small towns like Luther are now trying to fill budget gaps to make up for lost sales tax revenue now that Walmart has pulled out. (AP Photo/Sue Ogrocki)
