I have an old Nectar card that I haven't used in years but DS recently bought something from Argos and "donated" his Nectar points to me and I realise I have quite a lot of points on it.
What can I do with them these days? Is it literally just money off at Sainsburys or Argos or is there some cunning way to make them go further (I thinking like the Tesco clubcard scheme which I'm more familiar with).
