Though they do have dual pricing which means it's worth getting a card in

I don't know what the discount is for cardholders but there was a
programme on while I was living there at the time that they started
bringing in the scheme. One of the consumer organisations had monitored
prices in the lead up to the introduction and reported that there was an
increase in prices in the three months or so before the introduction of
the scheme which was matched by the savings cardholders received.

Wonder when Tesco will start doing the same.
