Target is a national chain that offers its weekly circular both in print and online. Target's online ad site automatically detects the user's location and serves the closest Target store's local ad. Kroger and Walmart are two other major chains that offer this service.
Smartphone apps such as Flipp allow users to access weekly circulars from multiple stores. Flipp supports over 400 stores, including Walmart, Kroger, JCPenney, Target and CVS. Flipp includes shopping list functionality, allowing users to cross-reference their shopping lists with weekly ads.
