I love this app! It has saved me so much money and introduced me to products I would not normally try. The app is very easy to use and has a simple layout. Various products are available, such as drinks, snacks, laundry and even caviar! Some of these products are free, and others has a small discount applied. All you need to do is check the app before shopping, write a list (or use the favourite tab in the app) and purchase the item. There is a barcode scanner to confirm that the product is the right one if needed. You need to keep your receipt and take a photo of this as well as scan the barcode to claim your cashback. It is normally same day confirmation for me, and I choose paypal as my cashback method, but i think bank transfer is applicable too. Would highly recommend this!
