Dunnes don't have the equivalent of Tesco's self scan system? I find that very handy in Tesco if I'm trying to hit a particular price tally - e.g. when using a One4All gift card where the till total needs to be less than or equal to the balance of the card. For some reason if it exceeds it they can't facilitate payment of the excess using another payment method.trying to maintain 2 separate tallies in my head!
