Recognizing that smartphones are becoming the go-to device for making shopping lists and finding deals, Target recently beefed up shopping list features in its mobile application with a bigger focus on deals and offers. The mass merchant updated its iPhone application with the new features last week as a follow-up to the app’s relaunch last fall, when lists were featured prominently. The latest update includes the ability to add Cartwheel offers directly from a list in the Target app.
