What have M&S done to the Sparks card?
Now you can’t ever get 20% but have to buy things to ramp up rewards which are in £ but only when you buy the from the category they send you.
you then have to convert it so that you can actually spend it.
i get the way it works but psychologically I would be buying more if I had 20% off a category or just in general as you get the reward right there and then.
Not a good move in my opinion
