You can setup Price Alerts for any item you are viewing by tapping on the three dots at the bottom of the Product Overview. Price Alerts will notify you if you would like to know when an item drops in price. By tapping Edit you can set the alert price to be any value you want and add specific attributes to the item such as free shipping or mail-in rebates. From the Price Alert section you can also swipe left over an item and add it to your Cart or Wish List.
