The line comes from Army of Darkness, the 1992 Evil Dead sequel starring Bruce Campbell as Ash Williams, a housewares clerk at the fictional S-Mart store. Fans picked up the slogan because it turns Ash's ordinary day job into part of his swagger, and clips of it circulated on video sites and soundboards long after the film's release. It endures because it is short, quotable and instantly signals a shopping joke, making it a handy shorthand in memes, reaction videos and edits about buying, selling or finding a bargain.
