Treat Yourself to a Three-Minute Save A Lot Shopping Spree

Enter Sweepstakes for the Chance to Sweep the Aisles of Your Local Save A Lot

Save A Lot, one of the largest discount grocery chains in the United States, is celebrating back to school with a national sweepstakes* in which one lucky winner will receive a three-minute shopping spree at their local Save A Lot store. Now through August 19, customers are encouraged to enter the sweepstakes one of two ways - in the Save A Lot Rewards App or by mail-in entry. One lucky winner will win a chance to sweep the aisles after a winner is randomly selected August 21.

“Who wouldn’t want to dash through the aisles and fill their cart without checking a price tag?” said Katie Kobus, Vice President of Marketing at Save A Lot. “We’re thrilled to offer one lucky winner the opportunity to stock up on groceries – on us. And while only one customer will take home the grand prize, everyone can count on Save A Lot for everyday low prices on the quality groceries they need.”

Save A Lot focuses on offering everyday low prices on great tasting, high quality private label brands as well as national brand products, USDA-inspected meat cut fresh in store, farm-fresh fruits and vegetables, and other non-food items.
