>>> For the Premium Credit Card you collect 1 Clubcard point for every £1 spent (£1 minimum) . . .
So, if you only used the card in Tesco, you'd need to spend £15,000 per year before you started making any profit from your Clubcard points (up until then you'd simply be using them to pay off the fee).
Let's say that you did, indeed, spend £15k in Tesco and a further £20k on your card elsewhere. You'd get a total of £200 in Clubcard points but, because of the fee, your actual profit would only be £50.
So, as I see it, the Premium Card would only be of value if either:
(a) you're so wealthy that you can routinely buy luxury cars (etc) using a credit card (which also means that you'd have to have a massive credit limit to do so!) ; or
(b) you're buying for a commercial enterprise using your own credit card. (e.g. someone running a big hotel might find such a card very useful)
