Just thinking about what is still really good value or good to have.
Top of the list for me is a rail card. I’m in the SE so am lucky to be able to get a Network Railcard, dp has a Two Together card and ds has a YP Railcard. My card paid for itself within 2 journeys.
Not exactly the same but thank goodness for the Boots Advantage card, still the GOAT loyalty card imo.
