Sensible approach Annie. I'm stunned that anyone is carrying around more than £50 cash and debit and credit cards. Sort it out Kate and Adam or somone will crack you around the head and take that off you.
I have three cards that I use but never ever carry more than one on me. Cash is a weakness for me but now I've disciplined myself to only making cash withdrawals from the same ATM so I can track them better. I carry around one of the cards, a bunch of loyaylty cards and never more than a fiver and that if I really really need to pay cash. I'm trying to phase it out of my budgets.
