This app is so confusing and inconsistent. You save normal points vouchers which then get used automatically but you need to scan double up vouchers at the till. Saw some people confused by this last week with double up vouchers not applied.. If you scan to shop you seem to need to save the points vouchers before you get your scanner. The items on the save list are still there after you pay for several minutes, so you have no way of knowing if they worked or not.
