Good: clean interface that allows you to get different offers that are somewhat tailored to you  Bad: the app does not provide your card’s barcode to be scanned, despite providing your membership number. This wouldn’t be huge, but you forget your card there is no way to key in the membership number at self checkout tills and the workers are (understandably)not keen to key it it when other customers are waiting. Once a barcode is added the app will be completely fine.
