Chain’s 2008 store redesign leads to new drive-thru opportunities In the December 2009 issue of Convenience Store News, Brian McKee, vice president of merchandising and co-owner of Pak-A-Sak Inc., spoke about the Amarillo-Texas-based chain’s success with a 2008 store redesign. Working with design firm Paragon Solutions, Pak-A-Sak had built a large, upscale store featuring drive-thru service. Shoppers who pulled up to the drive-thru could view a mini c-store, complete with a six-door beverage cooler holding a sample of everything in the 5,000-square-foot building’s main cold vault. That drive-thru accounted for one-third of the location’s total inside sales.
