Price compare items.
And then create a shopping list.
The app will alert you when items drop or new items are released.
Shopsavvy is an app for comparison shopping.
When you're in a store, scan a barcode to see if an item can be found elsewhere for less.
If they can, they can purchase it directly through the app.
The free Shopkick rewards frequent shoppers with points just for stepping through the door.
Rack up more by scanning various items or filling out surveys.
Redeem the points for gift cards.
