Flipp
Unlike a number of other discount apps, Flipp does not become redundant throughout the year, but it does come to life during the holidays. You would be best off using it to accumulate and study Black Flyer and Cyber Week ads as soon as they come out, which is generally a couple of days before the actual holiday, depending on the store and retailer. The app works with over 800 participating retailers, including big names like Macy’s and Walmart.
