The Boots app is terrible, really slow and jumpy and when you wish to pay thru the boots app with your advantage card points it asks you for the last 3 digits of it. Its on the first page obviously and drops you out!!! If you are booking through the boots app with your card attached surely the technology links it, it already told me what points i had but then wanted 3 digits. That's fine if the tech guys can sort without dropping out when you hit the home page for your card number.
